How to practice on the computer keyboard How to practice? Remove keys on the keyboard

The keyboard entry system in the computer is composed of:

keypad;
light indicators;
internal controller;
transmission channel;
keyboard controller.

The pressing of the keys on the keyboard panel calls out the closing row and column of the matrix of contacts. These numbers are transmitted to the internal controller, the scan code of the pressed key is deformed, which interface channel is transmitted to the keyboard controller. When this is formed and transmitted to the processor, the signal is reset, which informs the computer system about those that the key is pressed, then, it is necessary to complete the process.

Keyboard keys are divided into two groups:

command keys- recognized for the submission of codes of critical signals and the inclusion of special modes of entry;
alphanumeric keys- used for entering alphanumeric characters on a computer.

In the middle of the 19th century, if the computer was not yet around, the Drukars machine was found. The first typewriters, what to write, were not perfect, and with a quick set, it was sticking importantly. In order to "rule out" the situation, a special layout was invented, which took away the name qwerty(behind the name of the letters of the third letter row, I am beginning to be angry). The essence of the layout was in the fact that the letters, which are most often sharpened, were placed on "weak" fingers - the little fingers (along the edges of the keyboard), and the most rarely sharpened letters - were placed in the center of the keyboard (in the region of the fingers). Here you can read about the so-called blind ten-finger method on the keyboard.

Then the quality of the typewriters gradually improved, then the computers appeared, but the sound is strong - the QWERTY layout has been lost to this day. For the sake of justice, I should say that the alternative was broken up later Dvorak layout like a step-by-step approach to the standard QWERTY, but not a total extension.

In Latin Cyrillic, the layout of the boulder was broken down in an ergonomic mode (if the letters, which are often scribbled, are scribbled in the center of the keyboard) and victorious until this day, practically in a permanent look.

As we have said before, when the button is pressed, a scan code is generated and transmitted to the keyboard controller. The controller has installed a coding system and it is possible to recognize the pressed key before it. As soon as the command key is pressed, an additional signal is sent to the system. As soon as a letter-numeric key is pressed, the appropriate character generation code is selected from the ROM of the video controller for display on the monitor screen.

When expanding the computer, IBM stuck 8-bit coding for entering information from the keyboard - that's a total of 256 possible codes. The skin code was assigned its own graphic image. The basis of the league is a set of characters ASCII(American Standard Code for Information Interchange), which is the addition of characters, as IBM recognized for the need. Part of the symbols can be entered by pressing keys, part - by a combination of keys.

In order to adapt the code table to the Cyrillic alphabet, the "Russification" of the input system was broken. For which, Russian letters were applied on the official keys, and a special change was made to the character generation system of the controller.

When writing a sheet or entering numerical data, the keyboard is the main tool for entering information into the computer. But do you know that the keyboard can be played and played by a computer? There are more than a few simple keyboard commands to help you work more efficiently on your computer.

In the article, we can look at the basics of working with a keyboard.

Key organization

Keys of the keyboard are divided into sprat groups, fallow in functions:

Dial buttons (alphanumeric). Number of keys include the keys themselves with letters, numbers, signs and symbols.
Keys keruvannya. The number of keys are victorious okremo or in different combinations for chanting songs. The most commonly used keys are CTRL, ALT, the Windows logo key and ESC.
Functional buttons. Functional buttons are selected for typing special tasks. The stench is designated as F1, F2, F3 up to F12. Functionality of these keys is the difference between the programs.
Number of keys are victorious for moving documents and editing text, as well as web pages. They include arrow keys, HOME, END, PAGE UP, PAGE DOWN, DELETE and INSERT.
The numeric keypad is manual for the manual entry of numbers. The keys are grouped in a block, like a big one.

The next illustration shows the placement of these buttons on the secondary keyboard. Keyboard layouts may vary.

Shortcut keys

Successful keys - a way to follow the help of the keyboard. They are called keyboard shortcuts, for the stink of a robot. Deisno, maybe even a team that beats a mouse, you can beat a beat for one or a few keys. I need to learn at an early stage to master them.

In most programs, you can choose to use the dії for the help of the keyboard. To learn commands from the received keys, open the menu. Poednannya, yakshcho stench є, vіdobrazhayutsya order іz menu items.

The plus sign (+) between two and more keys indicates that these keys can be pressed at each other. For example, in Firefox browser CTRL+N means "press and press CTRL, and then press N". CTRL+SHIFT+W means "press and press CTRL and SHIFT, then press W".

For the help of the keyboard, you can open the menu and select commands and other parameters. If you press ALT at the menu program, one letter at the menu skin name will become underlined. Press the key with the sub-armchair letter to open the menu. Press a key with an armchair letter to a menu item to select the appropriate command.

For example, in the Firefox browser window, press ALT+F to open the "File" menu, then press the "H" key to select the command "Open new window"

Key combinations of keys

Let's take a look at the most beautiful keys. Use the keys to let the robot work with the computer, which is facilitated by the need to often win the mouse. Bazhano їх not just read, but obov'yazkovo zastosovuvat for an hour of work at the computer. І Nezabar you sing, as if it were handy.

Numeric keypad to place numbers from 0 to 9, arithmetic operators + (addition), - (addition), * (multiplication) and / (split), as well as a dozen to whom like on a calculator or a literal machine. If you want q characters to be duplicated by other keys, placing them on the numeric keypad allows you to quickly enter numerical data or mathematical operations with one hand.

To enter numbers on the numeric keypad, press the NUM LOCK key. There is a light NUM LOCK indicator on the large keyboards. When NUM LOCK is turned on, the numeric keypad functions like another set of navigation keys (the function is shown on the keys in order of numbers and symbols).

The numeric keypad is used for simple calculations, for example, in the Calculator program.

Otzhe, we looked at all the keys, which can be played. Ale for the sake of the most famous ones, there are three more important keys on the keyboard: PRINT SCREEN, SCROLL LOCK and PAUSE / BREAK.

PRINT SCREEN (or PRT SCN)

A long time ago, this key rightly beat those that are written - it sent the text on the screen to the printer. Today, PRINT SCREEN captures the image of the entire screen (“screen icon”) and copies it to the clipboard in the computer's memory. You can insert (CTRL + V) the image of Microsoft Paint or another program and, as necessary, expand it.

Don't understand SYS RQ on the same PRINT SCREEN button on other keyboards. Historically, SYS RQ was conceived as a system request, although the command was not included prior to Windows.
Please! Press ALT+PRINT SCREEN to capture an image of only the active window, not the entire screen.

SCROLL LOCK (or SCR LK)

In most programs, the SCROLL LOCK pressure does not affect anything. In some programs, pressing the SCROLL LOCK keys changes the behavior of the keys with arrows, as well as the PAGE UP and PAGE DOWN keys; The pressing of these keys allows you to scroll the document without changing the position of the cursor or the seen fragment. On the keyboard, there may be a light indicator of SCROLL LOCK.

PAUSE/BREAK

Tsya button vikoristovuetsya rarely. In some old programs, the onslaught of the tsієї keys caused the program to start, or in the old CTRL, the її vykonannya hit.

On some modern keyboards there are multimedia keys, which allow you to quickly, with one push, remove access to programs, files or commands. In other models, there are volume regulators, a scroll wheel, a scale wheel and other adjustments. Detailed description of these functions div. at the documentation with the keyboard or the computer or on the website of the compiler.

The correct use of the keyboard will help to overcome the pain and injuries of the hands, wrists and front, especially when working with a computer. The axis of the kіlka is pleased, how to solve problems.

1. Rotate the keyboard on the same level. Shoulders may be relaxed.

2. Place the keyboard in front of you. Like on the keyboard there is a block of digital keys, in the capacity of the center you can accept the key of the probe.

3. Hands and wrists, when typing, freely move over the keyboard, moving away the keys without pulling fingers.

4. Do not put on the palms or the wrists on the surface. Like on the keyboard there is a support for the palms, swear by it, it’s not enough to sort through the typing.

5. When typing, tap the keys lightly and trim your wrist straight.

6. Relax your hands, as you are not friends.

7. Working on a computer, work on short skin breaks of 15-20 minutes.

We have already learned from you. Now the time has come to turn on the keyboard. In order to write a sheet or ask for a search system on the Internet, we can’t do without a keyboard. Until then, if you don’t have a mouse, you can play the keyboard. Enough to know a few simple commands. Helpful programs and hackers don't work like a bear. Their main instrument is the keyboard. It’s possible, you know, if you practise, but for now, we’ll base the robots on the keyboard for the time being.

Keyboard shortcuts

The entire keyboard, including functions, can be visually divided into sprat groups:

Function keys (F1-F12)- vykoristovuyutsya for vykonannya spets_alnyh zavdan. If you re-press on the same key, then it hits. The F1 key - calls for the finalization of the program, in which you change at the given moment;

As long as you have enough knowledge about the keyboard. Find a skin key on your keyboard and try it in a game.

The computer keyboard is the main attachment for manual input of information, commands and data. At this article, there are attachments of the keyboard, layout, recognition of keys, symbols and signs.

Computer keyboard: the principle of diy

The main functions of the keyboard do not require special software. The driver required for the robot is already in the BIOS ROM. Therefore, the computer reacts to the commands of the main keys of the keyboard as soon as it is started.

The principle of the keyboard is as follows:

When a button is pressed, the keyboard chip generates a scan code.
The scan code is located at the port, integration at the motherboard.
The keyboard port tells the processor to reboot with a fixed number.
Otrimavshi fixing the number of the reset, the processor turns up to special. the area of operational memory, which is to avenge the vector of reparation - a copy of data. The skin of the record to the list of data should be sent to the address of the program, which services are being rebuilt, which are working with the number of the record.
After signing the program entry, the processor will proceed to the end of the program.
Then the program for rebuilding sends the processor to the keyboard port, where to know the scan code. Dali, under the crucifixion, the processor determines which of the symbols it recognizes for this scan code.
The worker corrects the code at the keyboard buffer, telling about the processor, then attaching its robot.
Processor to go to the next task.
The introduction of the character is saved in the keyboard buffer, the program does not take it away, for some purposes, for example, the Microsoft Word text editor.

Photo of computer keyboard and recognition of keys

The standard keyboard has more than 100 keys, divided into functional groups. Below is a photo of the computer keyboard with a description of the groups of keys.

Alphanumeric keys

Alphanumeric keys serve to enter information and commands that are typed after letters. The skin key can be used in different registers, as well as designate a few symbols.

Changing the register (introduction of small and large symbols) is assigned to the Shift key. For a hard (fast) change of the register, Caps Lock is used.

As the computer keyboard is forced to enter text data, the paragraph is closed by pressing the Enter key. Dali, the introduction of data begins with a new row. If the keyboard is typing to enter commands, Enter ends the entry and starts typing.

Function keys

The function keys are arranged at the top of the keyboard and are folded into 12 buttons F1 - F12. These functions and power lie in working programs, and in certain types of operating systems.

The key function of some programs is the F1 key, which prompts you to do it, you can recognize the functions of other buttons.

Special keys

Special keys roztashovanie order from the alphanumeric group of buttons. Through those who koristuvachі often go as far as vikoristannya, the stench mayut zbіlshenie rosemіr. Before them one can see:

Viewed earlier Shift and Enter.
Alt and Ctrl - wick in combination with other keys of the keyboard for the formation of special commands.
Tab is selected for tabulation when typing.
Win - opens the Start menu.
Esc – command line of a pink operation.
BACKSPACE - shoyno shoyno introduced symbols.
Print Screen - friend of the streaming screen or saving the image in the clipboard.
Scroll Lock - toggles the robotic mode in some programs.
Pause/Break - suspending/restarting a threaded process.

Cursor keys

The cursor keys are right-handed in the alphanumeric panel. The cursor is a screen element that is displayed on the input field. Keys from the kazіvniks move the cursor at the direction of the arrows.

Additional keys:

Page Up/Page Down – moving the cursor to the side up/down.
Home and End - move the cursor to the cob or the end of the flow row.
Insert - traditionally switches the data entry mode between insert and change. In other programs, the Insert buttons may be different.

Dodatkov digital keyboard

Additional numeric keypad duplicates the numeric and other keys of the main input panel. For її voicing it is necessary to turn on the Num Lock button. Also, the keys of the addendum keyboard can be tapped for keying with the cursor.

Remove keys on the keyboard

With the onslaught of a successful success of the keys, the same command for the computer is beaten.

Parts of the keystrokes:

Ctrl+Shift+Esc – open the Dispatcher's task.
Ctrl+F – open a search in the active program.
Ctrl+A – see all content in the selected window.
Ctrl+C – copy vision fragment.
Ctrl+V – paste from the clipboard.
Ctrl+P - view a friend of a streaming document.
Ctrl+Z – scaling the stream line.
Ctrl + X - view the visible plot of the text.
Ctrl+Shift+ → see the text behind the words (ear of space for the cursor).
Ctrl+Esc — open/close the Start menu.
Alt + Printscreen - screenshot of the active window of the program.
Alt + F4 - closes the active program.
Shift + Delete - permanently delete the object (cream cat).
Shift+F10 – shortcut menu of the active object.
Win + Pause - system power.
Win + E - launch the explorer.
Win + D - zgortaє usі vіdkritі vіkna.
Win+F1 – launches Windows finalization.
Win + F - Click for a joke.
Win + L - blocking the computer.
Win + R - open the "Starting the program."

Symbols on the keyboard

Singingly, richly koristuvachіv marked symbols for nikіv and other social measures. How do you create symbols on the keyboard, how can there be no explicit keys for whom?

You can install characters on the keyboard with the help of Alt-codes - additional commands for entering attached characters. Qi commands are entered simply by pressing Alt + the number in the tenth number system.

Often you can use food: how to build a heart on the keyboard, a symbol of the inexorability of the euro on the keyboard?

alt+3=
Alt+8734 = ∞
Alt + 0128 = €

Numbers and other symbols on the keyboard are presented in tables like small ones. The Alt-code entry has a numerical value, after entering it, when you press the Alt key, a sign will appear. The stovpci symbol has a final result.

Respect, as if the additional numeric keypad is not enabled - do not press Num Lock, then the combination of keys Alt + number can lead to inconsistent results.

For example, if you press Alt + 4 in the browser, without Num Lock, then the front side will appear.

Rozdіlovі signs on the keyboard

Sometimes koristuvachs, trying to put a punctuation mark on the keyboard, do not recognize those on which they scored. It is due to the fact that the difference in the layout of the keyboard transfers other types of combinations of keys.

Looked below, how to put different signs on the keyboard.

Rozdіlovі signs with Cyrillic

» (paws) - Shift + 2

] (right square bow) - "Ъ"
((left curly bow) - Shift + Russian letter "X"
) (right curly bow) - Shift + "Kommersant"

Computer keyboard layout

Computer keyboard layout - a scheme for attaching symbols of national alphabets to specific keys. Changing the layout of the keyboard is dependent on the program level - one of the functions of the operating system.

On Windows, you can remember the keyboard layout by pressing Alt+Shift or Ctrl+Shift. The typical keyboard layouts are English and Russian.

If necessary, you can change or add a new keyboard in Windows 7 by going to Start - Keypad - Yearbook, move and region (subparagraph "Changing the keyboard layout or other ways to enter").

In the window, select the “Move and keyboard” tab - “Change the keyboard”. Then, at the new vіknі, on the "Zahalni" tab, press "Add and choose the need for my introduction." Don't forget to save your changes by pressing "OK".

Computer virtual keyboard

The virtual keyboard is just a program, or an addendum to enter the PZ. In addition, the introduction of letters and symbols on the computer screen behind the help mouse cursor is added.

The virtual keyboard is needed, for example, to protect confidential data (login and password). With the introduction of data from the sonic keyboard, there is a risk of interfering with information by spyware. Then, through the Internet, the information is transmitted to the attacker.

It is possible to know that zavantazhit virtual keyboard for the help of poke systems, but you won’t take a lot of time from you. If you have installed Kaspersky Anti-Virus on your PC, you can launch the virtual keyboard through the smut of the program, you can enter it to the warehouse.

Screen keyboard

The screen keyboard is ruffled on the touch screen of a smartphone, pressed against it with the fingers of a coristuvach. Some people call it virtual.

To launch the On-Screen Keyboard in Windows 7, go to Start - Use Programs - Standard - Then Special Features - On-Screen Keyboard. Looking out in such a way.

To change the layout of the keyboard, use the appropriate buttons on the date panel (date after hour, at the bottom of the monitor screen).

Why work, why not work the keyboard

If your keyboard has stopped working raptly - do not hurry to get confused, back to back what caused the breakdown. All reasons, through which it does not work, can be divided into hardware and software.

At first glance, as the hardware part of the keyboard was broken, solving the problem without special skills is even more problematic. Sometimes it’s easier to replace it with a new one.

First of all, say goodbye, it was given, with a faulty keyboard, reverse the cable, as if it was connected to the system unit. Possibly, vin trohi vіdіyshov. As for the cable, everything is safe, change the line, so that the breakdown was not caused by a software failure of the computer. For which restart the PC.

If the keyboard does not show a sign of life after restarting, try rozburhati її for help of the obvious solution in Windows. The sequence of events is based on the Windows 7 application, as you have a different version of the Windows operating system - follow the analogy. The principle is approximately the same, maybe a few things change the names of the menu divisions.

Go to Start - Control Panel - Sound Settings - Device Manager. At the vіknі, if you have a problem with the keyboard, it will be marked with a yellow label with a hail sign. View її and choose from the menu Diya - Vidality. Close the Attachment Manager after you leave.

Go to the "Adjust sound" tab and select "Add attachments". If you search for your keyboard, and the driver will be installed.

If the installation was successful and the failure of the keyboard was due to a software failure, the Num Lock key indicator on the keyboard will light up.

If you don’t get away with injustice, then Timcha’s solutions can be.

In our days, the computer keyboard, like a mouse, is respected by a low-cost outbuilding. Prote їy vіdvoditsya an important role in the robotі z computer'yutor.

In most computer systems, the keyboard is a control panel, which operator enters data and tells the computer how to work with it. Most computers have a keyboard, with letters and numbers, guessing a different typewriter.

If you press the key of the Drukarska typewriter, the symbol is for example, the letter “A” is struck into the ink line, and the letter is written on the paper. The keyboard of the computer is foldable and rich; one and the same key can match a number of symbols and commands. The button simply triggers an electronic signal.

Under the buttons of the larger keyboards there are two sets of wires - horizontal and vertical. If the computer is activated, the microprocessor of the keyboard sends electrical impulses along the vertical wires to the signal. If a key is pressed, the wires under it stick together, flashing an electric lance. Tse show the microprocessor those that the key was pressed; the microprocessor re-verifies the horizontal wiring, so that the keys are changed, and the information is transferred to the computer.

Computer signal. The contact of two wires under the key closes the electric switch, signaling the microprocessor (violet color). The microprocessor knows which button is pressed, so the skin button activates only one pair of wires. At times, the key designates the letter "A", and the microprocessor generates a digital code: 10100001.

Folding attachment. If the key is pressed, the wires that are tucked under it send a signal to the microprocessor of the keyboard. The microprocessor registers a signal and recognizes an attack; at the same time the button is turned on the plate for an additional spring.

Start that scan. If the computer is switched off, the microprocessor of the keyboard (violet color) sends electric impulses (small pink arrows) behind the vertical wires (black color), ruffled keys (green color). Vіn scanuє zlіva to the right (great red arrow) zі swidkіstyu 1000 times per second.

The key is pressed. The onslaught of keys (left-handed) shakes the vertical and horizontal wires, which are used for scanning signals.

Organize and use the keyboard

Most computers have QWERTY keys (right-handed). Tsya name resembles a type of letter, roztashovannyh levoruch at the first row of the keyboard. The layout of the QWERTY letters was specially expanded in the first cars to increase the pace of the fast-paced people, so that traffic jams did not happen in the cars. At the keyboard of the computer, there are several keys. Data keys to enter letters, numbers and signs; shift keys vibrate great letters; control keys to the cursor move the cursor over the screen; function keys allow the operator to run the final commands with just one key press.
