Introduction:

• Computer is a system ,where the CPU and other peripheral devices are connected to eachother.
• Computer hardware is the collection of physical elements that constitutes a computer system.

Input hardware:

• A piece of equipment/hardware which helps us enter data into a computer is called an input device.
• For example keyboard, mouse, etc.

keyboard:

A computer keyboard is an input device used to enter characters and

functions into the computer system by pressing buttons, or keys.

Mouse:

The mouse is a small, movable device that

mouse

lets you control a range of things on a computer.

processing hardware:

The physical component of the computer that processes data and produces result is called processing hardware.

1. ALU(Arthomatic Logical Unit)
2. CU (Control Unit)
3. MU (Memory Unit)
