                   i +  TYPES OF COMPUTERS


                  All types of computers have a CPU, a keyboard and a screen to display the output. But
                  they differ in their size, cost and speed. Let us learn more about them.

                  Microcomputers


                  These computers are made to be used by one person at a time. Desktops, laptops, tablets
                  and smartphones are called Microcomputers. They are also called Personal Computers
                  (PCs).

                  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.
