                                                                              •  Features of a Computer




                                  I have seen a Computer at my school and my parents work on a laptop at
           6                      home. Both the machines are different in their sizes. But I don't know

                                  about different types of Computers.

                                 There are four types of Computers. Let me tell you about them.



                   Types of Computers



                  All types of computers have a CPU, keyboard, and a screen to display output. But
                  they differ in their size, cost and speed. Let us learn more about them.
                  On  the  basis  of  size  and  shape,  Computers  are  mainly  classified  Microcomputer,

                  Minicomputer, Mainframe and Supercomputer.

                    Microcomputer


                  These are the smallest computers. Their size ranges from a calculator to a desktop.
                  Any computer that has a microprocessor chip as its CPU is called a Microcomputer.
                  It is a single-user Computer.

                  Examples of Microcomputers are:

                  •  Desktop Computer                        •  Laptop Computer
                  •  Smartphone                              •  Tablet Computer
