                     •    The computer system is made up of two types of parts—hardware and software.

                     •     The parts of the computer that we can see and touch are called hardware.

                     •     The devices that are used to enter data into the computer are called input

                        devices.

                     •     The  device  that  work  on  the  data  (input)  from  input  devices  is  called  a
                        processing device.

                     •     The devices which help us to get these results or outputs are called output

                        devices.
