Minicomputers

             Minicomputers  are  mid  sized  computers.  In  terms  of  size

             and power, minicomputers are ranked below mainframes. A
             minicomputer  is  a  multiprocessing  system  capable  of

             supporting from 4 to about 200 users simultaneously.

             The use of the term Minicomputer has diminished and they
             have merged with servers.

                                            Microcomputer or Personal Computer

                                            A personal computer         is a computer designed to be used
                                            by one user at a time. The term microcomputer relates to

                                            microprocessor which is used with a personal computer
                                            for the purpose of processing data and instruction codes.

                                            These are the most common computer types since they
                                            are not very expensive.

               8  The  history  of  computing  devices  starts  from  about  5000  years  ago  in

                    Babylonia.

               8 The pascaline is known as the first mechanical and automatic calculator.

               8 In  the  early  17th  century,  John  Napier,  a  Scottish  mathematician,  invented

                    another calculating tool called Napier’s Bones.

               8 ENIAC  was  the  first  programmable  general-purpose  electronic  digital
                    computer.

               8 Minicomputers are used by small businesses and firms.
