Output units

Output units allow the computers to send the data to other users. Usually, a display device is considered as the output unit because it displays the texts, graphics, and other information. The common examples of output units are speakers, monitors, printers, etc.

Input units

The devices that are used to convey the information to the computer are called input devices. The primary examples of input units are a keyboard, pointing devices, audio/video devices, etc. With the help of input unit, a user can transfer the data to a computer for storing, displaying and processing data.

Some of the functions of input devices:

1. Pointing devices: This will allow you to point to the software on the computer and open it. It will interact with the graphical interface.
2. Keyboard: It will send the various alphanumeric data into the computer.
3. Audio/video devices: It will allow you to input the sound and pictures into the computer.


CPU is known as the brains of the computer. Without CPU a computer cannot work. It allows the computer to interpret and execute the various data through software and hardware. There are three various functioning of CPU. They are:
