                     A server is also a computer that provides data and other services to other computers. It is

                     used in offices where many computers are connected with each other.




                 Mainframe Computers
                 Mainframe computers are very large, fast, powerful
                 and  more expensive  than  the  minicomputers.
                 They can have multiple microprocessors  as their
                 processing unit.

                 Mainframe computers are generally used  in big
                 organisations where large amounts of data
                 is used such as banks. Examples of mainframe
                 computers are IBM zSeries, IBM 4381, ICL 39, etc.

                                                                                     Mainframe Computer


                                                                  Supercomputers

                                                                  Supercomputers are the largest and fastest of all
                                                                  types of computers. Even some supercomputers
                                                                  require much space as that of a floor of a building.
                                                                  The cost of supercomputer is very high. They can

                                                                  They  are  used  in  very  big  organisations  and
                                                                  government departments to do tasks such as
                                                                  weather forecasting and rocket launching. PARAM
                                Supercomputer                     was India’s first supercomputer developed in
                 1991. Some other examples of supercomputers are PACE, Titan, Sunway TaihuLight, Pratyush,
                 Mihir, etc.


                        SOME OTHER SPECIAL COMPUTERS


                 Apart from the types of computers that we have discussed in the previous sections, some other
                 types of computers are embedded computers and handheld computers. Let us learn about these
                 computers in detail.

                 Embedded Computers
                 An embedded computer is a special type of microprocessor based system that is developed for
                 performing a specific task. Let us learn about some of the embedded computers in detail.
