                  i +  COMPUTER SYSTEM

                 A computer system is made up of many parts. Each part of the computer performs a
                 different task. The computer system is made up of two types of parts—Hardware and
                 Software. The parts of a computer that we use to work with the computer are called
                 devices.

                  i +  COMPUTER HARDWARE


                 The  parts  of  a  computer  that  we  can  see and  touch  are  called  Hardware.  All input,
                 processing, output and storage devices form the hardware components of a computer
                 system. For example, keyboard, mouse, etc.
                 The hardware components are divided into four groups.

                 Input Devices


                 The devices that are used to enter data into the computer and give orders are called
                 input devices. Let us study about some of the commonly used input devices.
