    Supercomputers

                     Supercomputers are the largest and

                     fastest  of  all types  of  computers.
                     Even some supercomputers require

                     much space as that of a floor of a
                     building. The cost of supercomputer
                     is very high. They can process very

                     large amounts of data quickly.

                     They  are  used  in very  big
                     organisations       and      government
                     departments  to  do  tasks such as
                                                                                        Supercomputer
                     weather  forecasting  and  rocket
                     launching.  PARAM  was  India’s  first  supercomputer  developed  in  1991.  Some
                     other examples of supercomputers are PACE, Titan, Sunway TaihuLight, Pratyush,

                     Mihir, etc.
                     Embedded Computers

                     An embedded computer is a small computer system that is built inside another
                     device.  It  is  designed  to  perform  one  specific  task  for  that  device,  rather  than

                     general-purpose computing. It is also called a microcontroller.
                     Embedded computers are commonly found in devices like modern televisions, cars,

                     telephones, digital cameras, washing machines, microwaves and dishwashers. They
                     are also used in PDAs, printers, DVD players, VCRs, ATMs, thermostats, calculators,
                     video game consoles, digital watches and MP3 players.

                     These computers are very reliable and work continuously without interruption. They

                     take input from sensors and control the device’s operations automatically. Because
                     of their small size, low cost and efficiency, embedded computers are widely used in
                     home appliances, medical devices, security systems and industrial machines. They

                     make our everyday gadgets smarter, easier to use and more efficient.
                     Mobile Computers

                     Mobile computers are small and lightweight computing devices that are designed
                     to be easily carried from one place to another. They allow users to work, learn,

                     communicate and access information anytime and anywhere. These devices are
                     user-friendly, convenient to use and operate on battery power.

                                                                                            Evolution of Computers       15
