Golovna / Zahist

Rozіb'єmo parts of the computer on chotir main groups:

1. System block;
2. I will arrange peripherals.
3. Koshti manipulation;
4. Sobi vіdobrazhennya;

The system block, the main part of the computer, deducts the total number of processes. The system block can be folded and folded from various components. Qi components are looked at later.

Koshti manipulations: keyboard, mouse, game joystick. All those attachments for help, such as we "say" to the computer, how to work, how to run the number of processes at once.

Make sure you check the monitor before you. All information about the operation of the computer is displayed on the monitor. The monitor allows you to see what is being entered in the computer at once, by a kind of calculation process of occupied the computer.

Peripheral attachments - structurally water-based attachments to the system unit. Attachments that can control the power and work on the commands of the system unit. To serve for the sake of the tribute. You can bring printers, scanners, modems, external attachments to the peripherals, which you can remember.

Attachment to the system unit:

The motherboard is the main part of the system unit, to which all attachments to the system unit are connected. Through the motherboard, you can connect the system unit with each other, exchange information, and provide electricity. Shvidshe tires (channels linking outbuildings) of the mother's board;

The processor is the brain of the system unit, which performs logical operations. Vіd yogo svydkostі, frequencies are rich in why to lay the svidkodіya computer and yogo architecture.

Operative memory - memory for time saving of data from the computer, it is less likely to win if the computer is working. Vіd obyagu and the security of operational memory to deposit the code of the computer.

Hard disk - to serve for the trivial storage of information, on the new distribution of programs necessary for a robotic computer (Windows, Office, Internet Explorer.) and files of the mailbox (Shipping files, as well as mailbox client, video, music, pictures.).

A video card is a board in the middle of the system unit, assigned for linking the system unit and the monitor, transferring the image to the monitor and taking part of the charge for preparing the image for the monitor. Vіd vіdеоkarty to deposit the quality of the image. The video card can be loaded with RAM and its processor for image processing. The higher the frequency of the processor of the video card and the more memory of the video card, the more cool (less released) games you can play on your computer.

The sound card is designed for the preparation of sound signals that are produced by the speakers. The sound card is sounded into the motherboard, but it is also structurally plugged in and connected through the bus.

Merezheva card - a board, an attachment, it is installed in the motherboard or it will be installed in it. Merezha card is used for connecting a computer with other computers through a local network or for connecting to the Internet.

CD/DVD-ROM - device for reading/writing CDs, CDs, DVDs. Tsі pristroї vіdrіznyayutsya shvidkіstyu zchituvannya or recording іnformаtsії, as well as the possibility of reading / recording different wear. It’s important to learn about the sale at the same time, maybe we’ll be around the universal CD-ROMs. Suitable for CD-ROM and home reading and recording both CD and DVD in various capacities.

Drive - attachment, purpose for reading / writing information on a floppy disk. In modern computers, it is rarely installed. A card reader is installed in the disk drives of today's computers.

A card reader is an attachment for reading/writing information on a memory card. Card readers are concerned about the speed of reading/writing information. Card readers can be built into the system unit or are structurally independent, which are connected to the system unit via the USB port.

Ports of the computer - roses on the system block, assignments for connection of peripheral attachments, attachments of manipulators and attachments for displaying. We won't talk about the roses, we'll just review them: USB, VGA, Life socket, COM-port, Ethernet-port, Standard sound output socket, etc.

Living block - a block that lives in the middle of the computer. Blocks of life are getting stiffer. The tighter the living block, the more extensions you can connect to the middle of the system unit.

Coolers are fans designed for refrigerated cooling. The coolers are installed in the middle of the living block, on the processor, video card. An additional cooler can be installed on the system unit to cool the entire unit.

Radiators - metal plates, which are installed for the introduction of heat from the processors in the system block. Sound the radiators and cool down with coolers, but let it go.

Basic PC peripherals:

A printer and a scanner can be connected to the main peripherals of the computer. Purpose printer for displaying information from a computer on paper. Printers can be divided into laser and inkjet printers.

Strumene printers work on paper for help, farby, how to take it from cartridges. Printers can be completed with a different number of cartridges, everything depends on the model. Strumene printers, as a rule, are colorful. Є inkjet printer, which can take photographs. Deyakі photoprinters can be connected to the camera / phone directly, bypassing the computer. Not a lot of stremenevy printers - dear friend, ink from a paper sings with water.

Laser printers come in color and black and white. Laser printers work with laser change. Laser promin is used on paper toner, which is used from a cartridge on paper. laser printers Ring, laser printers stand at the offices, because. to think high swidkіst druk and not expensive for sobіvartіstyu drukush. Like inkjet printers, laser printers can print cartridges. Qi cartridges are refilled with toner (powder).

Scanner- Attachment for scanning documents, photographs and navit photo-negatives. The widest type of scanners is flatbed. Different scanners can vary the speed of scanning. Also, scanners can be divided for extensions, like stinks are removed when scanning. Active scanners install special attachments for scanning negatives. The scanner sounds connected to the computer via the USB port.

Rich functional add-ons - printer/scanner/copier (copier) in one add-on. Take care of all your functions. The rice of such outbuildings is characteristic, the possibility of using them as a copier, bypassing a computer. Such combinations of attachments can be like a streamer, and a laser.

Sobe manipulation:

The keyboard is the mouse, the axis of the main functions of manipulation, computer control. You can also use different joysticks, kermo with pedals, steering wheels, and ale stinks are mainly used for managing the gaming process. Here you can see that not all games that are released can correctly win, or you can win that other game manipulator.

P.S:

I want to vindicate your respect, so that progress does not stand on the ground, and tsya old age by the hour. But the architecture of the personal computer will not change so soon. To this end, the whole text will be curtailed, as an introductory part, for the presentation of computers more report.

Today, the world has new technologies for the production of old methods. Veterinarians and engineers are working on new vineyards. Ale "bicycle" has not yet been blamed.

Deyakі already zazjat opponents of the stone age to prophesy the swidka of the world of keyboards. The stench motivates us to replace the keyboard with the movement of the introduction. Obviously, it would be bad to say badly, ale є, first, different mov (do not denigrate, for example, Russian speak English), but, in a different way, not everyone can do without wiguks like “mmm…”, “uh…” , “tse… yak yogo there?…” ta in. All the same, I create problems in writing software, as it is possible to write in principle, but it is foldable, but that resource will be rich. At this stage, the development of personal computers to develop the most primitive system for recognizing movies, which would be sufficient to replace the keyboard, even capable of accessing system resources. Therefore, it is unlikely that in the nearest future it will be in the “stone age” (or, more precisely, we will see it), the keyboard will be generously occupied with the standard and, perhaps, the only way to introduce textual information. Before speech, but how, if the operating system is not yet occupied, go to the BIOS or install the system? Vbuduvaty podtrimku movy vnednya that in the BIOS? Well, earlier still oh yak far away.

Vykhodyachi z usky vyshchezazanogo, the choice of the keyboard all the same pridіlit deak respect. If you go to the store for a "non-revolutionary" outbuilding, pay respect to such factors:

ergonomics

Keyboard type

Ease of pressing keys

interface

Added capacity

Let's start in order. I didn’t put the ergonomics of the keyboard on the first place for nothing, because, in my opinion, it’s more important - if the keyboard is not handy, then it’s unlikely that the situation can be corrected by the Swiss processor and the video card is hard, and you can’t save more on the keyboard. Aja, it’s possible to type more than a dozen megabytes of text on it, but if you practiced a lot of text on a filthy keyboard, then it’s the fault of the nobility that the rest obscures the whole picture. And a lot of koristuvachiv, unfortunately, give them little respect and follow the principle “the cheaper, the better”. І more darma. If you want, from the other side, if you play in Unreal, then the number of keys is not particularly important, but press on good keys all the same, but it's not all the same time for Unreal to play! So don’t waste a little money on the dollar (I want, vtim, mayzhe not zustrich people who can “get” dollars) and buy a good keyboard.

Ergonomics

Under the ergonomics, you can understand all the power of the keyboard, as if you stand for clarity. We are negotiable only the most important of them.

Roztashuvannya klavіsh, as well as their form, rozmіri thinly. Keys that can change the shape and size of the world, splice: BackSpase, Enter, Shift.

There are two types of BackSpase keys: big chi small. More beautifully, zvichayno, great, it’s easier to drink in a new way, but at a price for the price, the keys are replaced with slashes down and, as a last resort, the small Enter key.

Yaka is so big. Ale rozmіrіv sіlkom їlkom vstachaє, to that, as me zdaєtsya, it's better, yakscho vrahuvat those, scho BackSpase becomes more. True, there are keyboards, some have large BackSpace, and Enter, and even short right Shift, which is even worse. As well as the Enter key is great, then there are also two possible options: for looking at the letter "L", turned to the next letter, and for looking at the letter "G". The remaining option is the best, so that the onslaught sounds on the near part of the key, and with the G-configuration, it is easy to hook the other keys.

As it happened earlier, it’s possible to change Enter and Backspace the Shift (right) key. It's not very important, because Shift wins often, especially in combination with other keys, and it's not easy to do it. For example, to change the layout of the keyboard, it is easy to change the combination Cntrl + Shift, but if the Shift is small, it is not so handy. True, you can fight with Shift "ohm, but if you have a friend, you can fight with two hands.

Therefore, choose a keyboard with large Shift and BackSpace and small Enter. A bad alternative is the following key configuration: small BackSpace, large L-like Enter, and large Shift key. Ale is the first option, like on me, shorter.

The keyboards with the so-called Eraze-Eaze configuration are sharpened, if the divisions into two halves have been made. One of them (on your choice) activates the probe function, and the other one - the BackSpace keys. It’s churned up for the sake of clarity, but the summation of the windings is super-accurate to the basic rule of blind typing; So I’ll leave the letter of the word to enter with one hand, then the offensive probіl - іnsha. Luckily, with Eraze-Eaze you can not program the halves, leaving the Space function for both (tried). Deyakі models of keyboards can mother zbіlshenu Escape. Qiu singularity can be brought up to pluses, even if you spend it lightly. It's true, it's so easy to get around, because Escape is always ripped apart.

At the call with the appearance of the OS, which allows you to wake up the electricity, on the current keyboards, ring (if you want and not ob'yazkovo wake up) three so-called keys to sleep, which allow you to sleep, wake up and turn on / turn off the computer. Chi will need these keys, swear to you, but still stink, give respect to them. There are three options: the keys are folded out of the scrolling keys in the bottom row, the keys are folded instructed by the scrolling keys in the top row, the sleep keys are folded over the Break group, when the Break group is thrown down and out of the line. The remaining version of the filthy team, if you have called for an attack on Insert (for example, Shift + Insert), then you can press PrintScreen into the buffer, and a picture of a megabyte by 3-4 or more will be loaded into the buffer (for example, Shift + Insert) I will allow the color palette), and then rub the front in place. Another way to expand is more “better” - when you press on the Insert key, you will actually press the button to release the live. Therefore, the first option, in my opinion, is the best.

For those who are victorious great and able to Russian language, it is important, as the Russian keyboard layout is vikonana and the Russian letters are applied in such a color. Cyrillic layout buvaє rosijska (Russian and russian typewritten) Typewritten layout, as if crying out from the name, repeating the keys of the other typewriter. Bula may be the standard before the advent of Windows, in which case a new layout appeared. The stench may be escaping, but in Russian small, but effective thoroughly, for example, the letter “e”, which may not be victorious, the bula was moved to a distant kut, and on the її place they placed a key with often victorious dot on the rose of the stench. top row and entered through the top register. , A foreign company provided us with a perfect layout.

The layout of the Cyrillic alphabet, obviously, to lay down only the driver's name (Windows after the installation, call May Russian, but you can also remember), and you can buy stickers, or just remember the roztashuvannya of the wrong letters. Ale chi varto zim to take care of? Therefore, choose the keyboard from the Russian layout. Until the speech, іnshі at the same time і are not allowed out. The color of the applied Cyrillic alphabet may also have an important meaning. More beautifully, zvichayno, red, to that the red color is very memorable, but in principle the stars are on the right. Wanting to win, singsongly, all one varto slap the red color.

Microsoft has been working on a new type of keyboard, recognized for Windows 95. This keyboard has been named the Natural Keyboard. The literal translation has a natural keyboard, the literary one has an ergonomic one. Nadalі tsya name became nominal. Natural Keyboard can be opened to the sides of a vertical row of keys that lie up to the area of the skin hand. Coristuvach relieves the tension of the trim of the hands in parallel one to one. The profile of the alphabetic part of the keyboard is a swollen arc. This allows for the need to trim the hands parallel to the table. Є support for the repair of hands. When I look at Natural Keyboard, it becomes clear that too many keyboards have simply subsided the conservative style of typewriters that they write. Natural Keyboard served as a model for succession. However, typists sometimes do not hesitate to call their keyboards ergonomic, even though they would like to look at the innovations of the original Microsoft keyboard. Maybe, there is only a small amount of such keyboards, like the stench is occupying. As you work richly with text and you are not limited by space, buy the most ergonomic keyboard. The next thing to note is that the stench is more expensive for the money.

Nadalі z'appeared the opening of the keyboard, which regulate the turn of the two halves. The skin is half of your own legs, so that you can regulate the frailty of other lines. The deyakı went farther away and saw the keyboard, which is formed from two halves. It might be better to do it manually, but you can’t put such a keyboard in a hacker style on your knee.

The palm rest, which appeared in MS Natural Keyboard, has been expanded to include more keyboards. Vaughn is recognized for the rearing of the hands, and not for their working position: it is necessary to follow the rules of the penzle of guilt and hanging over the keys. That's why it's called Palm Rest. However, why do you need to follow these rules, spiraling and with robotic wrists on the steel (I myself fall for such)? For the rest, the support will be quite easy, especially for different high keyboards. The stand also enhances the old look, especially if the vikonan is in a different color. Stands are water-reinforced and lit. It was clear that the stand, that it is supported - a bigger solution, that allows you to safely switch to the keyboard without a stand. If the support is fixed, then it’s good, because it’s small, that it allows a certain turn of the fastened lines, so that with a sickly keyboard for help, the support didn’t work on evils. Choose keyboards with backings that are waterproof. Respectfully, the hand rest is sold as an accessory, so keyboard owners without a stand can get it at any time.

It's easy to send your harn to the robot to the basics. Vikoristovy form, raztastovanu below

Students, graduate students, young adults, like victorious base of knowledge in their trained robots, will be your best friend.

Entry

For all the hours, people needed to rejoice. In the misty prehistoric past, the stench was puffed up on the fingers, or the bumps were on the brushes. Approximately close to 4000 years ago, at the dawn of human civilization, they were found to complete a collapsible number system that allowed them to develop trade areas, develop astronomical cycles, and conduct other calculations. After a sprat of a thousand, the first manual counting tools appeared. And in our days, the most complicated calculations, like the impersonal other operations, would be used, not related to numbers, to rely on the help of the “electronic brain”, which is called a computer.

Fahіvtsі, maybe, do not forget to remember that the computer is not a brain (recognize, for the time being, - specify the deeds). It's just one more tool, one more attachment, inventions in order to make our work easier.

The development of outbuildings for the introduction and maintenance of data is a practical area, which is closely tied to the calculation theory and technology. Historical roots are far better, lower computers, and smarter computer scientists have been engaged in development. Known by engineers and engineers, the effective implementation of two main power - how to enter data and instructions into the computer and how to extract the most detailed information in the most manual form - has been adopted by the created various hardware and software programs. Winemakers allowed to expand the scope of stosuvannya kom'yuterіv mayzhe inter cheloveka ї vyav - in the form of a detailed design of a piece brush to vikonnannya musical creations and management of "nekerovanim" letak.

Added capacity

Ergonomics

Under the ergonomics, you can understand all the power of the keyboard, as if you stand for clarity. We are negotiable only the most important of them.

Roztashuvannya klavіsh, as well as their form, rozmіri thinly. Keys that can change the shape and size of the world, splice: BackSpase, Enter, Shift.

2. Keyboard type

membranes

Nap_vmekhanіchni

Mechanical

The name of the membrane keyboards is similar to the fact that when pressing the keys, two membranes are locked. Turning the button is made with a gum dome (with a shaft in the center). The membranes sound like discs on a plastic swimmer, vikonan in a different way. For the bottom of the membranes, serve as an intermediate liner with openings. That is why in the speeches they often write "plіvka" or "plіvkova klavіatura". Since the membranes are located on the inner sides of the slabs, the construction is well protected, for example, like poured kawi. In the larger protection implementations, everything looks like a single gum kilimok with domes, which protrudes, ruffled under the keys. To the pluses of such keyboards, you can see low noise, ease of pressing keys, protection from other objects and roads, low price. The only shortfall is the lesser durability among other types.

Napіvmekhanіchnih keyboards have more longevity (up to 50-100 million pressure) and metal contacts, which are not wiped, in expensive models the stench can be gilded. Everything is placed on a different payment. The key is rotated by a gum dome. In a different way, the mechanical keyboards are similar to membrane ones. The axis only cost the stench more expensively.

In mechanical keyboards, the button is turned by a spring. The disadvantages of such a mechanism are related to the airtightness and road safety. For example, purification from spilled kawi took about an hour. Well, the truth is, these models are outrageously, ale stink more expensive. A plus is durability and suppleness, especially if the contacts are gilded, as well as the vіdsutnіst vtomi (so it’s practical not to lie on the pressure on the pressure, which can’t be said about the mechanical and mechanical keyboards).

In my opinion, mechanical keyboards can have more shortcomings, lower gains. In the first place, the stench is weakly protected, in a different way, it makes louder noise, lower membranes, that one is richer and more expensive. Therefore, choose between the membranes and the mechanical ones as soon as possible. To the point, the number of keyboards for bagatma parameters are identical, to that the choice here is most often determined by the price. But the truth is, napіvmekhanіchnі dovgovіchnіshi, аlе аlе аlе expensive membrane саn you сає tає tає tаіnki (here close 20-30 mln. rush for good models), sho if it breaks, then all other components of the computer will already be on the call.

The keyboards can be used without clicking or without. In the literal translation, click (click) - clatter. It is realized by a thin arcuate plate under the key, as if bending like a riven. The click allows you to accurately guess that the key is pressed and do not skip letters when typing. Click like a rich coristuvacha, but better yet, buy a keyboard that works really well, and don’t enrage your robot and other people with all sorts of clapping. Sound the click on the mechanical keyboards (the oscillators change little of their variability), and also on the keyboards of other types.

There is one more type of keyboards – touch keyboards. The principle of її dії foundations on the basis of different potentials, which is added to one element. The number of these elements corresponds to the number of keys. Like sensitive elements, there are stream-conducting contacts, which look like two plates separated by a small gap. At the moment of finger sticking of the contact maidanchiks, the statistical potential is supported by a similar scheme, at the output, a signal is formed that is similar to the signal of the sound keyboard. The touch keyboards are unique, because there are no mechanical elements in them, but for the little stink of that stench it is worth remembering, lower sounds. Since the electronics are covered with a ball of polymer slick (symbols are also applied on it), the touch keyboard may be protected from the outside swells. True, as wide-width, similar outbuildings were not taken away from the connection with the unhandled vikoristannya and the road, so you can only get it on the great industrial enterprises at the virobnicheskie shops, that is rare.

Ease of pressing keys

In my opinion, which is easier, which is better. Easy onslaught allows, with less effort, to make a move and not to miss letters. When buying, press the keys, match with other keyboards. Remember that you can, if you happen to push on the button, do it a lot, then why not make your life easier?

3. interface

Uses three interfaces: AT, PS/2 and USB-interface. AT already installed and bought the keyboard with such a socket varto, as if the motherboard is covered for the connection of such a keyboard.

Well, if you have an ATX motherboard, there may be another rose for the keyboard, PS / 2 titles. Therefore, choose a keyboard with a PS / 2 socket on the end of the cable.

In the rest of the hour, attachments for USB tires, including keyboards, became popular. The cream of the possibility of a hot connection / inclusion of the stench does not allow for obvious advantages, but it costs more dearly. Ale, even if it's pennies, then a shorter keyboard with a USB interface, a lower one with a PS / 2 (would like to see that such a keyboard is a modern one). Speaking of which, prices on USB keyboards are steadily dropping and, perhaps, will soon be on par with great keyboards, and that's one more plus. However, before it drops enough, it is unlikely that USB will be effectively objectively harmless.

If you are neophyte (so you love everything new) and call the USB greed, then you need to choose whether you want to convert the keyboard to a USB hub or not. On the right, the USB keyboard can have a few USB ports (1, 2, 4) for connecting other peripheral devices in a lanso. In my opinion, typing the keyboard like a hub is not handy, to the one that the keyboard sometimes has to crash, and then all the cables pull after it, which is not handy.

Nareshti, the keyboards are without wires and wired. The keyless keyboards are folded with the help of the keyboard and priymach, which is based on the high-frequency radio waves. It’s also transmitting that the vicorist is infrachervone viprominyuvannya, but the stench didn’t gain a great expansion through those that direct contact of the annexes is needed for the functioning of the annex, and the greater expansion of the radio keyboard. If you like playing in Unreal, or if you want to type, lounging at the armchair and putting your feet on the table, then the arrowless keyboards will give you such a possibility. In other cases, they are the most important, and the axis is not obvious - it is necessary to change the batteries, do not obstruct the transmission with objects, through the filthy way the radios and so on penetrate. Until then, such keyboards cost more expensively for the sounds. And if you just can't get the cable to fit, you can get more keyboard support for help.

Added capacity

Prior to the advent of Windows, our keyboards were limited to 101 keys. Then three more keys were added: two keys to the shortcut of the Start menu and one key to the shortcut of the context menu. It is unlikely that their presence is possible as an additional ability, shards of stench have become standard. But at the same time on the keyboards you can use a lot of other additional keys and buttons.

Internet buttons. Burkhlivy development of the Internet, causing the appearance of pop-up buttons. Call the stench to use the following functions: connect to the Internet, access the job site, and exchange the mail. The number of such buttons is different: from zero to two tens. Buttons ring out at the top, above the function keys. As you often surf the Internet, one-click buttons can save you an hour.

multimedia buttons. Multimedia here means everything. These buttons allow you to play with multimedia programs, including: increase or decrease the volume, mute the sound, go to the next / forward track, start engraving, increase the pause, end the engraving, hang the disc. Some of these buttons are smaller and have fewer functions, while the buttons are programmed for current functions. As you often use multimedia players, you can set your choice on the keyboard with multimedia buttons. Respectfully, the multimedia buttons have changed the interpretation of the multimedia keyboard: previously, the combine was called that because of the built-in speaker and the volume control (such and at the same time). Regardless of those who can hypothetically think of keyboards with okremi groups of buttons, it is practical to release keyboards or only with keys for sleep or for us at once. At times, the keyboard is all the same called multimedia, also multimedia means the presence of all keys.

Sound additional buttons are implemented physically, which will increase the price of the keyboard. And yet, it is an original solution, if only one button is entered - the MF (Multimedia Function) jumper, so as to translate multimedia 12 function keys. Such keyboards, for example, at the BTC company. Genius has a button called EasyKey, but the sensation is the same. Deakoy neruchnistyu є nebhіdnіst peremikatisya. Another simple way to add programming keys is to use them in one key added, as if playing chords with the essentials. The butt is the Fn key, which is on other keyboards. The chant for chords is Fn+functional.

There are more keyboards with different add-ons for introduction. For example, a keyboard with a sensory indicator is shown on this little one. I am especially unaware of the recognition of such outbuildings - it is too expensive to cover the stench, but they cannot replace any sensory panels there. Try playing in Unreal with the help of such a Touch Pad! It’s unlikely that you have a video, that one for office zastosuvan, Touch Pad, maybe not the best solution. bar code (trade code, which is often used on packages), the stench is displayed for RS, which is used as a commercial device. in the middle of which there are 6 floating points, covered with a gumi ball.

Some models of keyboards for changing the layout can be used as a compact digital block, if the keys are not duplicated, and the block of keys of the Break group is changed to the beast. Others may be the mother of the digital block. In some cases (like nothing else) it is possible to connect to the keyboard of the additional block with numeric keys.

In other types, the dimensions change for the size of the change between the keys and / or the speed of the outer edge. Another way is not shkidlivy, but the first one can’t get in, because with a change in the number of keys between the keys, it’s possible to start typing with a friend. It’s even hotter, if the buttons can also change the volume.

Well, nasamkіnets all sorts of rubbish, but yakі tezh even more important. In the first place, the method of drawing on the keys is a little one. Good keyboards make little ones, wink for the help of a laser, on cheap wines of farboy applications. Friend, zvichano, gershe, wanting farba tezh stays for a long time.

Give respect to the presence of zachipok on the keys "F" and "J" and on the key "5" of the digital block. If few people want to be greedy with them, but if the devil is not hot, maybe if you learn how to make a fool of yourself. Before that, at the same time, you should step in and out, help you to look up (if the screen is black, turn on the light, and you need to enter the password to enter the password). Also, prostegte, schob on the keyboard bouli step out.

One s vymog on the periphery є їхнє low vpromіnyuvannya. In other words, what is more important (to be more precise, less important, but the radio-active keyboard itself cannot control visible damage to health), the radio receiver does not tremble and ship near the periphery. Guilty but compliance with the American FCC standard (part 15, subpart B, class B), which appears in the documentation, and also applied to the back of the keyboard. On this parameter, you can not use your respect, but the shards, if any, are bigger and smaller, the virobnik prepares only such keyboards. For lovers of trimming the keyboard on the knees, we can recommend models with a metal bottom.

The service keys can either be turned into a darker color, or they may not look like alphabetic ones. Vibir is only distinguished by your relish - here it’s a smut, it’s fitting.

Give respect to the visible yak_st viroba. As if with the first dot, or with another slick pleat, the plastic begins to creak, as the scuffs are visible on the ridges, as the writing is clearly indistinct, then it is unlikely that such an attachment is a variant of respect. Even better, as the seller guarantees his goods. Ring out this term no more than fate, ring out the scarlet - just as the keyboard correctly proprated one river, then, more for everything, it’s more common for a long time, so, obviously, don’t blame it on the flowers and don’t bathe in the lava. If you spilled on the keyboard, for example, kava, and it stopped working, then you can try to beat the board and wash it under a strong stream of water (of course, before installing it back, the board needs to be dried). Imovirnist, scho keyboard earn here 50%.

Instructed by the keyboard, Misha is also the most important addition to the introduction. Vlasne, such are the keys, on niy roztashovani. For help, you cannot enter textual information (so do not take other software-emulators of keyboards), but the headline is the same.

The principle of moving mice is even simpler: two sensors move the mouse horizontally and vertically, and based on the data, the driver of the mouse forms a cursor on the screen.

Use three types of mice. Tse:

Mechanical, in which the main element is sensors, which are used to check the bags. Mechanical sensors, called mice. After all, the movement of the mouse does not move so smoothly, that longevity is also small. To that, the oskіlki їkієє їkh zalivaє bazhati kraschogo, and komіvartіst not nagagato lower for optomechanіchі mice, practically all virobniks pinned their release.

Optomechanical. Analogous to mechanical ones, but the bags are guided by optical sensors. Such mice are overpowered, universal (they can be practiced on any even surface, cheap, they have become too wide, and the stench itself will sound victorious.

Optical. The optical mouse sends a light to the obscurity of the surface, and after the fermentation, the light goes back to the mouse and there it is analyzed by electronics, like in the fallow in the characteristics of the captured signal and in the presence of two straight lines of the bear’s hand, running either on the ridges of the fall, or on the other hand. The achievement of such a mouse is even higher than the arrogance, the reliability and the smoothness of the movement. The minus is that the price of such a bear is equally high, as well as those that need to be trimmed all the time її squeezed to the kilimk (otherwise the surface), otherwise the cursor collapses there, where you are tempted.

It needs to be said that earlier optical mice were beaten only with a special kilimk from the mark on the new one, which sounded at once from the mouse itself. Now progress has been made in my gallery, having allowed the creation of optical bears, which can be practiced practically on any surface. Here the optical sensor is a video camera of its own kind, and when the mouse is awakened, the processor is working to capture the song at the same frame rate, analyzing the results, and directly indicating the mouse’s speed. The lack of technology means that if the processor does not have the necessary code, then when the manipulator moves too fast, the cursor starts to behave in an inconsistent manner. However, for good (and so expensive) bears from cym, sound everything. It is possible to note that the optical target does not work on translucent and diffracting surfaces, for example, on the shield or the surface of a CD.

Another important characteristic of the mouse is the way to connect to the PC, so that the interface. Previously, the COM-interface was mainly used, now the standard is PS / 2. There are no special differences between them, but you can’t do anything to the PS / 2 port, nothing else, except for the mouse, the mouse with a 6-pin round PS / 2 socket. It is only necessary to indicate that in old computers there is no such rose, and here there is one - a mouse for a COM port with a 25- (more) or 9-pin socket on a short cable.

Also USB mice are covered by the USB bus. The stench is better for others, because, in the first place, you can take care of more calls in one hour (about the end), and, in a different way, you can turn them on with a working computer, which is especially important for portable PCs. True, the bears for the COM port can also be attached for a hot connection, but if you want to use PS / 2, you can, or you don’t need it for silent mirkuvan, so it’s so easy to burn the port. Until then, USB-mishі suchasnіshi. The axis is only a price rozcharovuє ... Until it falls to the level of mice "not USB", then, in my opinion, it will not be possible to say unequivocally that the mice for USB are richer. And if you have an antique computer, then there is only one choice - COM.

Now I told you about the warnings. Razdіlna zdatnіst misha vіmіryuєtsya in dpi and shows, skіlki vіdlіkіv (impulses, on how it is broken it is passed in_dstan) to kill the mouse with the passage of one inch. Obviously, the larger, the shorter, the larger scales allow the cursor to be more accurately positioned, and the cursor becomes more smooth. It is normal for the size of the mouse to become 200-900 dpi. With this accuracy, of course, lie in the rozdіlnoї zdatnosti screen of the monitor and the shape of the swidkostі ruhu. Before the speech, the increase in speed by way of setting the additional options in the control panel did not show the increase in dpi, as it matters, the driver simply sets one view more than the screen pixels. When working in low resolutions, it’s not so easy, but with high resolutions, the cursor starts to collapse with commemorative haircuts, which are already fighting, especially when working with smaller objects, so either buy a good mouse, or put a low division of the building, or change the shift .

Optical targets can be set at 1000 dpi and more, so with different settings, the cursor can be positioned exactly at high resolutions of the screen and the maximum speed of its movement. Otzzhe, as a penny, choose optical mice, shards of stench can cause the most among all mice. Unfortunately, the dpi parameter doesn’t show much, but, as a rule, it can be determined by the price - why won’t it be more like a misha yakіsnіsha (more precisely, now: what a misha yakіsnіsha, tim is more її price).

Insha river, skilki in the form of a mouse can be done in a second. It’s not possible to lie down already in the mouse, like in the interface. For mice with COM and PS / 2 interfaces, the number is more than 40, and for USB it is more than 100. This parameter specifies, how smoothly the indicator of the mouse can collapse with її shifts (the most shifts of the mouse itself). With full displacements, this parameter does not have a special value, since it is 40 per second as a whole, but when it is, let’s say, in Unreal Tournament, it’s even more true. Let's say you play in a separate building 1024x768. Here it’s up to you to come up behind you and insert a rocket at the place. If you lost your life, then no more than in one second you need to turn around 360 degrees and give a blow to the front, otherwise you won’t kill him. It doesn't matter if the mouse connected to the PS/2 port will collapse the screen in “portions” of at least 25 pixels. And if you aim at 25 pixels, then you will have a miss. Well, it’s true, use utilities that can smash a mouse (it sounds funny: smash a mouse) and increase the number of responses per second from 40, let’s say, up to 60. With a good effect, it’s not easier to win a USB-mish, how about it?

Previously, there was a Bus Mouse name that beat the system bus. The stinks were sold at once with their expansion cards and small special roses. At the same time, such a decision has become old and we will not report to it on the new one. Let's just say that old laptops can be damaged by Bus Mouse.

If tailed animals do not suit you, then bears will be born without tails. Like keyboards, stinks can vicorist either infrachervone or radio industry. Stay, obviously, more beautifully, to that which can be practiced for the availability of a direct line of sight with a catch. Just don't forget to change batteries. It seems, to the point, that such a mouse does not work like a battery, so the battery gives 1.2 V instead of 1.5. I don't know, I didn't check it myself.

A standard mouse has three buttons. The two-button buttons are even wider, so the third button is practically not victorious. Ale, more bears can be different, and no more additions. Most of all, it’s a lot, which allows you to scroll instead of the window. Zvichayno, tse zruchnіshe, lower ticks with a vkazіvnik along the line and pull it down. Therefore, choose mice with a ring. It can be ripped either on the side, or in the middle - for a skin-friendly setting. More mice can have additional buttons (type 1 to 40), which can be assigned to different functions. If you don’t respect them, then, I’m guessing, you won’t need the stench, but only to get it.

Another cіkavim raznovidom teddy bears є її vidozmina at the look of the phone. The telephone there is a special one, it is connected to a special telephone socket. So that two darts did not come out of the mouse, they sounded together into one, but went to the telephone cable and the cable of the mouse bounced in a small small block, to which everything is connected. You can speak for the help of a loud call, without being distracted by the main occupation, for which the "michetelefon" may have a speaker and a microphone. Such an original solution is a great alternative to both the great and miniature phone, which, for example, hangs on the monitor. Since there is nothing foldable and expensive in these outbuildings, then stench can be made at a very affordable price (approximately the style, the phone with the same functions and the similar mouse), so the bears can be even more brown for those coristuvachiv, like they love to talk on the phone view the screen.

A small variety of mouse-like manipulators is a trackball (Trackball), which in essence is the bear itself, only turned upside down. The transfer of the cursor is done with the hand of a bag (more precisely, a bag, so that it is bigger, lower at the mouse). I especially think about the summability of such an attachment (maybe it’s the one that I just didn’t respect it at all), but wine is a good alternative for quiet coristuvachi, whose style of forcing those cups with those other accessories. If you are such a koristuvach, then savage respect, so that the corps will be made massive and not shoveled on the table, but a great sack. Please note that the trackball is especially handy when working with graphics programs, as it allows more precise positioning of the cursor. Maybe it’s something wonderful, but the trackball can also be dartless.

Choose the bears of the great rose. It’s even unacceptable, if it’s constantly waving from the hands. Good, if it’s not over there, then it’s easier for her to accept the ruin. That one vzagalі in the mouse, everything can be good, to that which is not handy, but the filthy worker Misha is already obscured by all those who didn’t work for you. Kilimok tezh may be great and handy. Not long ago, kilimki appeared with a gel cushion for the wrist, but, like on me, the bunny only conquers the nervousness. Before the speech, especially if the misha is optical, the kilimka’s replacement is better to win the arch paper - we’ll make it better, we’ll add the rubbish, fat and pet (it’s really important if you play in Unreal) wine is not bad. And if you get lost, it's easy and not bad to replace it with a new one.

CRT monitors (Cathode Ray Tube) are the widest type. As you can see from the name, all such monitors are based on a cathode-promenade tube, or, as it seems in the literature, an electron-promenade tube (ELT). The technology, which is victorious in this type of monitors, was created richly fatefully, and on the other hand, it was created as a special tool for vimiryuvannya zmіnnogo strum, simply kazhuchi, for an oscilloscope. The development of this technology led to a later date before the creation of monitors.

The CRT monitor can hold the tube in the middle of a vacuum. From the front side, the inner part of the tube fold is covered with a luminophore (luminofor). As a luminophore for color CLTs, it is possible to finish folding warehouses on the basis of rare earth metals - іtryu, erbіyu, etc. Luminophore is a cere- mony, which makes it bright under the hour of bombardment with charged particles, in this case with electrons. It is worth respecting that some luminophore is called phosphorus, but it is not correct, because the phosphor, which is victorious in CRT coverage, does not have anything to do with phosphorus. In addition, phosphorus glows as a result of interaction with sour weather when oxidized to P2O5 for a few hours. To create an image in a CRT-monitor, an electronic harmonic is vibrated, as if impromptu the flow of an electronic crystal on the inner surface of the glass screen, as if it was covered with different-colored phosphor dots. The flow of electrons on the path to the frontal part of the tube will pass through the intensity modulator and the fast system, which is based on the principle of potential difference. As a result, electrons accumulate great energy, part of which is stained on the light of the phosphor. Electrons are spent on a phosphor ball, after which the energy of electrons is transformed into light, then. The flow of electrons hums the points of the phosphor to glow. The color dots of the phosphor that glow, shape the image, as you see on your monitor. As a rule, a color CRT-monitor has three electronic harmonics (the skin glows with its own luminophore, which can shine with one color - black green or blue, which is often called RGB (Red, Green, Blue) based on EPT, but not even more correctly, the shards of the RGB-principle are victorious in other monitors, and in the outbuildings, as they can reach the monitors even farther away). One harmata stagnates in monochrome monitors, which practically do not vibrate at a time, and few people can hear it.

To understand, like working an electron-promenev tube, it would be wrong to guess physics. As already mentioned, the basis of її is formed by three electronic harmonics, like letting out electronics. For the help of the Coulomb forces, the electrons are blown and in such a manner are created around the beams of the necessary directly. A special system is involved in the maintenance of electronics, which is performed. When the skin of three beams gets on your luminophore, the light of the skin from them comes out. From these three colors, as you can see, it is possible theoretically to take any color vision with a way to change the strum of the skin from three electronic exchanges, which are used on the triad of points. Theoretically, it would be easy to create such a complete system, even though in practice good kinescopes can create such a large number of colors that it is unlikely that the “average statistical” human eye can distinguish them. Since the beam is one and thin, then to create a new frame, you need to move the beam across the screen. Moreover, it is necessary to work hard, because the phosphor dots do not shine for long, and before the stink fades, it is necessary to activate them again. Svіy hіd promіn starts from the upper left kuta and step by step sygaє lower right.

Schob EPT showed those that are necessary, and not those that I want, the necessary electronics are needed, as it indicates the quality of the monitor. Before speech, the very difference is like keruyucha elektronika, which are created by different vibrators, is one of the criteria that determine the difference between monitors with the same electronic-promenu tube. It was understood that the electronic promise, for example, for red phosphor elements, is not guilty of adding green or blue color to the phosphor. In order to achieve such a vision, a special mask is created, the structure of which is to lie in the type of kinescopes in different types, wanting, singly, a wider type of kinescope (as well as its versatility, image quality and other parameters) to lie in the type of mask. EPT can also be divided into two classes - with delta-like scaling of electronic harmonics and with planar scaling of electronic harmonics. These tubes can have different masks, about which it will be told further. With this tube with planar spreading of electronic harmonics, it is also called kinescopes with self-aligning changes, so it is practically the same when adding the magnetic field of the Earth to three planar spreading of the change, and when changing the position of the tube to the field of the Earth, it is not necessary to carry out additional adjustments.

Shadow mask is the most wide-ranging type of masks for CRT monitors. The shadow mask is folded from a metal mesh in front of the glass part of the tube with a phosphor ball. As a rule, most of the current shade masks are made from invar (invar, an alloy of zinc and nickel). Open in the metal space as an aim (even though it’s not exactly accurate), and the same care will be taken by those who use the electronic industry only on the necessary luminous elements, or less in the singing areas. The shade mask creates gates with uniform round openings, so you can easily pass through the electronic change. The name “thinova” is not rightly correct, for those who look farther away the masks will also be shaded, but for tradition, the mask at the sight of the grate from round openings is usually called shade. Since it’s cheap to make a shadow mask and give a bad quality image, then kinescope is the most popular with it. The shadow mask is installed on most monitors Hitachi, Panasonic, Samsung, Daewoo, LG, Nokia, Viewsonic and others.

Shchіlinna mask (slot mask) - tse technology, which is widely used by NEC under the name of CromaClear. In this way, the luminophore elements are shaded at the vertical elliptical centers, and the mask is broken from the vertical lines. In fact, the vertical smugs are divided into elliptical centers, like a group of three luminous elements in three main colors. The minimum gap between two centers is called slot pitch. The value of the middle may be different horizontally and vertically. The smaller the value of the slot pitch, the more natural, the greater the clarity of the image on the monitor. The width of the mask is reversed, around NEC monitors (de middle elliptical), in Panasonic monitors with a PureFlat tube (previously called PanaFlat). Before speech, the first monitor from a flat tube was Panasonic itself from a PanaFlat tube. LG in their monitors has a vicor flat tube Flatron with a size of 0.24 mm (similar to Trinitron, which you can read about below, this technology is not available). Respectfully, the flat tubes Infinite Flat Tube (DynaFlat series) like Samsung do not have a thin mask, but a strong shade. Tubes with a slit mask, as a rule, are absolutely flat and give a clearer image, lower kinescope with a shadow mask.

What is a computer made up of

For good reason, mentally, the entire computer can be divided into several main groups.

System block;
Take care of the information;
Sobi manipulation;
Peripheral outbuildings.

System block , tse naigolnіshe at the computer. Yogo can be matched with a tulub that head. Do you reveal such a monster, with cool whiskers? All calculations and processing of information are taken into the processor itself. Tse is not a simple attachment. Why wines are added up, we can look better.

Take care of the information tse, obviously, monitor. If it’s possible we don’t need wine, but for the time being we haven’t learned to take information only for additional signals. On my own monitor, I’ve bachimoly processed the information by the processor, I’ve understood the language for us, and on my own in pictures, numbers, and letters.

Sobi manipulation (Do not confuse with the help of mass information). Before them one can see the keyboard, mouse, game joystick, kermo too. For the help of tsikh koshtiv mi, we give the command to the computer, and make the manipulation to translate these commands into a machine mov, as the computer understands. So, the computer can make its language, as only a programmer can understand.

Peripheral outbuildings - Tse attachments that can manage well, but also work on the commands of the system unit. Before such extensions, one can have such a possession, like a modem and other external storage facilities. The computer can do without them, but for us, such an attachment will make life easier.

Powering the system unit:

Motherboard - The largest and most important board in the middle of the system unit. Itself before it connects the computer attachments, as if it won't provide electricity, and exchange information with them. Attachments, which are located in the processor block, are connected to the mother's payment for additional special roses. Qi rozn_mannya are called tires. Check the speed of the tires

- The brain of the computer. The same wine vikonu uє logical operations. Vіd yogo svydkostі that frequency lie svydkodіya computer'yutera.

(otherwise, how is Yogo called - Winchester)- serve to collect information. In order for you to be able to save on your new data (folders and files), the hard disk must be formatted on a new operating system (Windows, Linux, etc.). Once the operating system is installed, you can install other additional programs, such as Office, browsers (programs for working on the Internet), Photoshop and others.

– a fee assigned for the processing of video signals that are transmitted to the monitor. Without qієї pay, we can't see anything on the screen. A modern video card can have its own microprocessor and its own operational memory. The greater the memory, and the greater the frequency of the work of the microprocessor of the video card, the shorter the image and the faster the change of the picture. It is especially important for cool games. The video card is already built into the motherboard or I will charge the motherboard.

Sound card – circuit board for processing sound signals. A lot of current computers are already built into the motherboard.

Merezhevo map vikoristovuєtsya to connect the computer to the local network. At the same time, it’s already a lot of someone creating a local network in themselves, so that all members of this family could work out of foreign documents and go to the Internet, independently one kind of one. The Merezhna map can also be budged.

, serve for reading and recording CDs.

cardreader– attachment for reading and recording information on all memory cards (telephone, camera, video camera, etc.). Card readers are also concerned about their read/write characteristics. The stench is buoyed into the system unit or called (they are connected via the USB port).

serve for supplying and distributing electrical energy for all motherboards and connecting to it outbuildings.

The axis of such components is the basis of our love computer. Vychayte yogo and vikoristovyte at your goals to the fullest.

Peripheral outbuildings. Peripheral extensions - extensions, structurally water-reinforced in the system block. Attachments that can control the power and work on the commands of the system unit. To serve for the sake of the tribute. You can bring printers, scanners, modems, external attachments to the peripherals, which you can remember.

Sobi vіdobrazhennya. Make sure you check the monitor before you. All information about the operation of the computer is displayed on the monitor. The monitor allows you to see what is being entered in the computer at once, by a kind of calculation process of occupied the computer.

Motherboard. The motherboard is the main part of the system unit, to which all attachments to the system unit are connected. Through the motherboard, you can connect the system unit with each other, exchange information, and provide electricity. Shvidshe tires (channels linking outbuildings) of the mother's board;

Hard disk. Hard disk - to serve for the trivial storage of information, on the new distribution of programs necessary for a robotic computer (Windows, Office, Internet Explorer.) and files of the mailbox (Shipping files, as well as mailbox client, video, music, pictures.).

Video cards. A video card is a board in the middle of the system unit, assigned for linking the system unit and the monitor, transmitting the image to the monitor and taking part of the charge for preparing the image for the monitor. Vіd vіdеоkarty to deposit the quality of the image. The video card can be loaded with RAM and its processor for image processing. The higher the frequency of the processor of the video card and the more memory of the video card, the more cool (less released) games you can play on your computer.

CD/DVD-ROM. CD / DVD-ROM - an attachment for reading / writing CDs, CDs, DVDs. Tsі pristroї vіdrіznyayutsya shvidkіstyu zchituvannya or recording іnformаtsії, as well as the possibility of reading / recording different wear. It’s important to learn about the sale at the same time, maybe we’ll be around the universal CD-ROMs. Suitable for CD-ROM and home reading and recording both CD and DVD in various capacities.

Card Reader Card reader is an attachment for reading/writing information on a memory card. Card readers are concerned about the speed of reading/writing information. Card readers can be built into the system unit or are structurally independent, which are connected to the system unit via the USB port.

Computer ports Computer ports are sockets on the system unit, designated for connection of peripheral devices, manipulator devices and devices for display. We won't talk about the roses, we'll just review them: USB, VGA, Life socket, COM-port, Ethernet-port, Standard sound output socket, etc.

Postscript I want to take back your respect, so that progress does not stand on the spot and tsia statya old times. But the architecture of the personal computer will not change so soon. To this end, the whole text will be curtailed, as an introductory part, for the presentation of computers more report. Today, the world has new technologies for the production of old methods. Veterinarians and engineers are working on new vineyards. Ale "bicycle" has not yet been blamed.
