Hybrid: This type of computer combines the features of both analog and digital computers.

                  It benefits from the speed of analog computers and the precision of
                  digital  computers.  Hybrid  computers  are  often  used  in  scientific
                  research and specialised fields. For example: Electrocardiogram (ECG)
                  machines used in hospitals to monitor heart activity.
                  Flight simulation systems used in aviation for pilot training and flight
                  analysis.
                  Purpose


                  On the basis of their purpose, computers can be of two types:
                       General Purpose Computer: These computers can handle a different tasks efficiently.
                     Examples include personal computers such as desktops, laptops, smartphones, and
                     tablets.

                       Special Purpose Computer: These computers are designed for a specific task and perform it
                     very quickly but cannot be used for other functions. They are commonly used for controlling
                     the process of manufacturing and for weather forecasting systems.
                  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 computer with a single microprocessor as its main processing unit. It's a
                  compact and affordable digital computer designed for use by one person at a time. Microcomputers
                  are also known as Personal Computers (PC). Some examples of microcomputers are:


                       Desktop: A desktop computer is designed for regular use and is
                     usually kept in one place on a desk or table. Its components, like
                     the keyboard, mouse, and storage devices, are connected either
                     by wires or are wireless. A desktop is not portable. It is commonly
                     used in schools, colleges, offices, etc.


                                                    Laptop: A laptop is a small, portable computer that you can
                                                    use while traveling.  It has an  integrated  monitor,  keyboard
                                                    & touchpad,  and  runs on a rechargeable  battery.  When fully
                                                    charged,  a laptop  can work  for 4 hours or more without
                                                    needing  to  be  plugged  in.  Laptops  are  especially popular
                                                    among professionals who travel frequently, such as marketing

                                                    executives.
