So that’s why today I thought that why not provide you, people, complete information about the type of keyboard so that all your doubts can be cleared. Then without delay, let’s start and know what a keyboard is called.

After this, the entered data is converted into machine language so that the CPU can understand the data and instructions that are coming from the input devices.

How is The Keyboard Connected to The Computer?

If we talk about earlier times, then PS/2 or serial connector was used to connect the keyboard with the computer. But if I talk about it now, then USB (universal serial bus) and wireless connectors are used right now.

Connecting them has become very easy now. The disadvantage of the Wireless Keyboard is that we have to change the battery again and again. Otherwise, it is more portable than other keyboards.

Keyboard Type

There are many different types of keyboard layouts that are manufactured according to the region and language. Today I am going to tell you people about those types.

QWERTY: This layout is used the most in the world and it has been named according to the earlier 6 letters which you can see in the earlier top row. It is often used in all countries. It is used so much that many people think that this is the only type of keyboard available.

AZERTY: It has been developed in France, according to each other variations of the QWERTY layout and it is also considered a standard French keyboard.

DVORAK: This layout is designed to reduce finger movement so that typing can be done faster and faster than QWERTY and AZERTY keyboards.

If I talk about it now, then the keyboards that are used at the present time are mostly ‘QWERTY’ only.

Keyboard Button Info

On the keyboard of a computer, many letters, numbers, symbols, and commands are located in the shape of buttons, and eight of them belong to some specific category. So if you come to know which category the key belongs to, then you can easily know about their function.

Some keyboards have special keys, while some do not, but all keyboards have the same alphanumerical keys.

Alphanumeric Keys

All keyboards have a set of keys called alphanumeric keys. The term “alphanumeric” means either letters or numbers, but does not contain symbols or command keys. These number keys are present in two different parts of the keyboard:

One above these letters and the other on the right of these letters. These number keys which appear above the letters are double symbol keys. If you press the Shift button and hold the number, then whatever symbol will be in that number key, will be typed. On the top row of the keyboard, there are letters such as “Q, W, E, R, T, and Y”. That’s why the keypads in cellphones are called QWERTY Keypads.

Punctuation Keys

Punctuation keys are called those which relate to punctuation marks. For example “comma key,” “question mark key,” “colon key” and “period key.” All these keys are located on the right side of the letter keys. Like the number keys, if you hold the punctuation key and press shift, then you can use another function.

Navigation Keys

On the keyboard, the navigation keys are visible between the letter keys and the numbers keys, which too on the right side of the keyboard. Navigation keys mainly have four arrows: up, down, right, and left. These keys move the cursor like a mouse on the display screen. With this, you can use these navigation keys to scroll through the website history.

Command Keys and Special Keys

Command keys are called keys that give commands such as “delete,” “return” and “enter.” It depends on your keyboard whether special keys are present in it or not. For example, to turn the volume up and down, move the videos back and forth, etc. Other special keys are “caps lock key,” “shift key” and “tab key.”

Types of Keys

Here I will inform you about the different types of keys located on the keyboard and will also tell you about their use. In a normal keyboard, the keys are divided into the following six categories on the basis of function. Whose description is something like this?

Function Keys

Function Keys are at the top of the keyboard. They are written on the keyboard from F1 to F12. Function Keys are used to performing a particular task. They have different functions in each program.

Typing Keys

These keys are used the most. Typing keys include both types of keys (alphabet and numbers), they are collectively called alphanumeric keys. Typing keys also include all kinds of symbols and punctuation marks.

Control Keys

These keys are used alone or with other keys to perform a certain task. In a normal keyboard, most of the Ctrl key, Alt key, Window key, and Esc key are used as Control keys. Apart from these keys the Menu key, Scroll key, Pause Break key, PrtScr key, etc. are also included in the control keys.

Navigation Keys

Navigation keys have keys like Arrow keys, Home, End, Insert, Page Up, Delete, Page Down, etc. They are used to move around in a document, webpage, etc.

Indicator Lights

There are three types of indicator lights on the keyboard. Num Lock, Scroll Lock, and Caps Lock. When the first light on the keyboard is lit, it means that the Numeric Keypad is on, and if it is off, it means that the Numeric Keypad is turned off. Second, the light tells us about the uppercase and lowercase letters.

When it is turned off, the letter is in lowercase, and when it is turned on, the letter is in uppercase. The third is known as Scroll Lock. It prompts us about scrolling.

Numeric Keypad

We can also call them calculator keys because a numeric keypad has almost the same number of keys as a calculator. They are used to write numbers.
