Input unit used for the entry of data in the computer. The basic work of input device is to enter the data in the system by converting man-made language into machine understanding language.
- Keyboard – By this, we can enter the alphanumeric data to the machine.
- Mouse – It is a pointing device by which the user can enter the graphic and arrow marking method.
- Trackball – This is another replacement for the mouse.
- Joystick – It is an input device which can move in all the direction.

This section of the computer is showing the memory and its types so there are 2 type of memory which are mentioned below.
Primary Memory –
This is the main memory of the computer where the data is currently used by the computer. It is of twp types.
RAM is a volatile memory that losses the data once the machine is switched off. This is fast as the data is at the use.
2: ROM : Read only Memory
ROM is non-volatile memory where the data is saved for a longer time and not erased even after switched off the device. This is a little slower than the RAM.
