Now, you have understood that computer is an amazing machine that can do

different types of jobs. It has different parts that work on a computer system.

A computer system is made up of hardware and software.

Hardware

Computer hardwares are the parts of a computer which you are able to touch

and see. The human body consists of different parts. Some of them are visible

but those which are inside cannot be seen. Similarly, in a computer, we can
see the parts of the hardware that are outside. They are attached to the CPU

by cables. Some parts of hardware are inside the CPU. You can only see them

when you open the CPU.

There are special types of hardware devices that are used to input words,

numbers or pictures. These are called input devices . The keyboard and the
mouse are the most common input devices.

Can a computer run without hardware?

There is no existence of computer without hardware. Almost all computer

systems require at least a disk drive (e.g. hard drive), monitor, keyboard,
mouse, memory (ROM and RAM), motherboard, processor, power supply

(SMPS), and video card in order to function properly. If any of these devices is

missing, an error would be encountered, or the computer would not start.
