Hybrid:  A hybrid  computer  is a special type  of computer  that

                     combines features of both digital and analog computers. It uses
                     the speed of an analog  computer  and the accuracy  of a digital
                     computer.  These  computers  are  generally  used  in  scientific
                     research  and  specialised  applications. The heartbeat  measuring
                     machine used in hospitals is  the most  common example  of a
                     hybrid computer.                                                             A Hybrid Computer
                  Purpose

                  On the basis of their purpose, computers can be of two types:

                      General Purpose Computer: A general-purpose computer is a type of computer that can
                     perform many different tasks equally well. This includes personal computers like desktops,
                     laptops, smartphones, and tablets. They are designed to handle a wide range of jobs efficiently.
                      Special Purpose Computer: A special-purpose computer is designed to do a specific job very
                     quickly and efficiently. It can't do other tasks. These computers are used for specific functions,

                     like controlling machines in factories or predicting the weather.
                  Size, Speed, Processing Power and Cost

                  Computers differ in size, processing power,  speed, and cost. On the basis  of these factors,
                  computers can be categorised as follows:
                  Microcomputer

                  A microcomputer is a small type of computer that uses one microprocessor as its main 'brain' for
                  processing information. It is a small and less expensive digital computer. This type of computer

                  is made for one person to use at a time. A microcomputer is also called a Personal Computer
                  (PC). Some examples of microcomputers are:
                      Desktop: It is a personal computer developed for regular use and

                     generally placed in a single location on a desk or a table. All its
                     components, such as a keyboard, mouse, and storage devices, are
                     connected through wire or without wire. Due to its size and power
                     requirements,  we  cannot carry  this type  of computer.  Desktop
                     computers are generally used in schools, colleges, offices, etc.                 Desktop

                                                     Laptop: A laptop is  a small  and portable  personal computer
                                                    that you can use while traveling. It's designed to fit on your lap,
                                                    and it has a built-in screen, keyboard, and mouse. You can use
                                                    a laptop anywhere because it has a rechargeable battery that

                                                    allows it to work without being plugged into power for 4 hours
                                                    or more. People like marketing executives who travel a lot often
                                                    use laptops.
