In order to use a computer, you need to know the keyboard identity and its usage clearly. Because if a user doesn't know about the keyboard, he can use the computer but can't work fast. Keyboards work differently in different programs. When we do something on the computer, we have to give input for it and we use the keyboard more to give input. There was a detailed discussion on how to input through the keyboard

The computer has different types of input devices, the most notable of which is the keyboard. We use the keyboard to provide most of the computer information and instructions. Almost everything for programming is done using the keyboard. There are different types of keyboards, but more than 104 keys are used. The key numbers on the previous keyboards were 99/100. However, there are currently 104 keyboard keys available.

In addition to writing with the keyboard, many other types of work are done. The keys on the computer keyboard are divided into six parts according to the type of work.

Caps Lock Key: - Normally when we want to write something on the computer, we need the Caps Lock Key to make that text small and large letters. Once the Caps Lock Key is pressed to make an English axis smaller and larger, everything that is written becomes a capital letter. If you want to make the text lower case, press Caps Lock Key to make it lower case. It is possible to enlarge the characters without pressing the Caps Lock Key. For this you have to press and hold the Shift Key and when you start writing any English letters, they will continue to be capital letters. If you do not press the Shift Key then it will be a lowercase letter again.
