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.

                  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.
                           Laptop

                       Tablet: A tablet is a small and portable digital computer that is smaller
                     than a laptop. Instead of a mouse, it has a touchscreen as its input
                     device. Like a laptop, it has a rechargeable battery. Tablets usually have
                     fewer features than laptops. They are often used by professionals in
                     different organisations.
