So, I will answer the question arising in your mind one by one and we will all know the information of computer keyboard in Hindi. Along with this, you will also get information about shortcut keys in this post.

Keyboard introduction:

A keyboard is an input device of a computer that has a variety of buttons. With which we put the data in the computer and give instructions to it. In it, the buttons are exactly like typewriters, but the functions are very much.

Many devices are connected in the computer which are very important such as input devices and output devices.

The keyboard is an input device of a computer which is said to be a very important device. Because the way a person becomes handicapped without a person's hand and foot.

In the same way, if it is removed from the computer, then the computer will also be disabled, that is to say that the computer cannot be used, without the keyboard the computer will not run. This is called keyboard in Hindi.

It is mainly used to enter alphabets, numbers, commands and different data in a computer.

It is a means of communicating directly with the computer. These CPUs process our entered data and then show us the results through output devices such as monitors and printers.

The keyboard can also do a lot of different functions with the mouse being an input device. You will know what the mouse is and how it works. But do you know that you can do a lot of work without a mouse only by this?

What is a keyboard called?

We often hear that there is an important input device in the computer without which it is not possible to work and its name is only known that it is a keyboard.

Don't know?

How many total buttons are in the keyboard?

The total number of buttons in any keyboard depends on its size. Nowadays we get many types of keyboards of different sizes.

Full-size keyboard

This type of keyboard has 104,105,108 buttons as well as a dedicated number plate.

Ten keyless Keyboard: This type of keyboard has 87 or 88 buttons which does not have a dedicated number pad.

75% keyboard

It also has the same number of buttons as the tenkeyless keyboard and it is quite small in size.

60% keyboard

This type of keyboard does not have a function row, that is, it does not have function buttons. Friends do not even have arrow buttons, their layout is very small and such a keyboard is rarely used.

How does a computer keyboard work?

It is an input device as well as a hardware device that works according to the instructions given by the user.

It is made up of circuits, switches and processors, with the help of which every keystroke message typed reaches the computer.

You should not understand that I am talking about the processor of the CPU, but the keyboard also has its own processor, which transmits every information to the system.

When we type anything in the keyboard, say if I type A, it causes a switch press. Pressing the switch completes the circuit and causes a slight current to flow.

When we press the switch, it causes a cube that is known as bounce which reaches the processor. It forms a key matrix from a large part of the circuit system.

Below the button we type, grids are made like a grid of small buttons and this is called a key matrix.

When the processor learns that a circuit has been closed, it compares the location of the circuit of the key matrix to the character map in the ROM. The character map is a comparison chart.

Which tells the location processor of each butoon key. In addition, it also tells the matrix location of the combination of keystroke. Like sometimes we press other alphabets with the Shift and Control buttons, this combination of keystrokes happens.

In this way, when we press A, there will be a current flow which will produce vibration, which will be known to the processor. Now she will place the circuit's location in the key matrix from the character chart of the ROM. Then it will know which button is pressed, thus it will display immediately by writing A in the output.

What are the types of keyboards?

There are different types according to its usage. Now we will know here what are these types. By the way, computers and laptop keyboards are simple, people know the same, but apart from this there are also gaming, ergonomic, thumbsize, numeric keyboard etc.

Apart from this, these devices are also many types such as foldable, laser / infrared, and chorded.

There are also different ways to connect this to a computer such as PS / 2 and USB. Let us now know what are these different types and how do they work.

Laptop keyboard

Generally it is made in V-Shape for 2-handed typists. This creates an angle, which also increases typing speed.

Laser or Infrared Keyboard

This is the latest technology in the computer world. With this technology, the projector is projected into the flat surface in the form of a keyboard light. Due to its light project, it is made on the table or desk itself.

You can input the alphabet into the computer by typing in the keyboard on the table or desk itself. By the way, this technology is still in the developing stage, so it is not being used regularly.

Rollup Keyboard

Rollup is the best used in travel. You can roll it and keep it open when needed. It becomes very easy to carry due to its rollup.

It is usually made of silicon and polyurethane material. The only advantage of this material is that you can rollup it, but do not fold it. This causes the risk of circuit damage.

Keyboard Layout

If you knew the meaning of Layout, then you must have understood what Layout is.

If you do not know, then let us know that according to different languages, its structure or texture is also made according to its own. Buttons are placed in different ways according to their own.

QWERTZ

The only difference from QWERTY layout to QWERTZ layout is that the position of Y letter is replaced with the position of Z letter in it. That is why it was nicknamed "Keyzboard". There are 2 big reasons for this change.

In German, the letter "Z" is more common than the letter "Y", due to which it is used more.

Also, according to German orthography, "T" and "Z" are always used in front of each other.

That is why both these letters can be typed very easily through index fingers.

AZERTY

DVORAK

Augustine Dvorak invention of DVORAK layout. It is arranged according to the use of letters.

For example, the letter "e" is the most commonly used letter, which is why it is placed in the center. This reduces the movement of the finger.

Compared to all other layouts, this layout has a lot of speed typing and is also comfortable for fingers.

Different Computer Keyboard Keys

You use this input device and it also has all kinds of buttons for your work. Then you will also know how many types of these keys are there. If you do not know, then you will get complete information about it further.

Typing keys

Typing keys are the same keys that we use to type normally maximum, such as alphabets and numeric keys. You have also read it above as alphanumeric keys. Apart from this, punctuation and symbols are also included.

Function keys

The top row has the function Keys. You can identify it as F1, F2 …… ..F12. Function Keys have different functions. Work is taken as needed.

Numeric keys

Numeric keys are keys that are numbers keys on the right side of alphabets. They are very useful in calculating.

Control keys

Control keys are keys that can be used single or can be used with someone else. St Ctrl, Alt, Escape, Windows Key etc are Control Keys. Apart from this, Scroll Key, PrtScr, Pause, Break keys are also Control Keys.

Indicators

The board has indicator lights for some keys. When these keys are turned ON, the lights which are for its indication remain ON. If the lights are off, the function that is connected to Keys will not work.

When NUM key is ON, the right side numerical numbers key will work, if it is OFF then it will not be typed. All the alphabets will be written in upper case when off key indicator light will be written in upper case.
