Minicomputers

                  These computers are small general-purpose computers with the

                  capability to serve a number of users simultaneously.
                  They are used for scientific and engineering computations, business

                  transaction processing, file handling, and database management.

                                                           Mainframe Computers


                                                           These computers are very large, fast, and powerful
                                                           computers. Some mainframe computers are so big
                                                           that they require as large a space as that of a room.
                                                           They  are  used  in  big  organisations  where  a  large
                                                           amount of data is used, such as banks.


                          Mainframe Computers

                  Supercomputers


                  These are the largest and fastest of all types
                  of computers. They can process a very large
                  amount of data quickly.

                  They  are  used  in  very  big  organisations  and
                  government  departments  to  do  tasks such as
                  weather forecasting and rocket launching.
                                                                                           Supercomputers

                      PARAM was India’s first supercomputer, developed in 1991.





                      To Sum Up

                          A computer system is made up of many parts.

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

                          The devices that are used to enter data into the computer and give orders are
                          called input devices.
                          The CPU (Central Processing Unit) is a processing device that works on input
                          and sends the result to the output devices.
