But there will be many of you who do not have complete knowledge about the keyboard. Therefore, understanding this post’s keyboard information in Hindi will be very helpful to those people.
So that’s why today I thought that why not provide complete information about the type of keyboard to you people so that all your doubts can be cleared. Then without delay let’s start and know what a keyboard is called.
What is a computer keyboard?
The keyboard is an input device. It is mainly used to enter commands, text, numerical data, and other types of data on the computer. A user uses input devices such as a keyboard and mouse to interact with the computer.
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 now, then USB (universal serial bus) and wireless connectors are used right now.
Connecting them has become very easy now. The disadvantage of Wiress Keyboard is that we have to change the battery again and again. Otherwise, it is more portable than other keyboards.
