Tablet: A tablet is a compact, portable computer that is smaller

                     than a laptop and uses a touchscreen for input instead of a mouse.
                     It has a rechargeable battery and typically offers fewer features
                     than a laptop. Tablets are often used by professionals  and are
                     handy for work on the go.

                                           A minicomputer, or "mini," is a powerful and costly computer

                                           compared to a  microcomputer.  It  can  contain one or more
                                           microprocessors and is used mainly for scientific and engineering
                                           tasks. Minicomputers can support multiple users at once and are
                                           often referred to as small or mid-size servers. For example, PDP-11,

                                           PDP-8, HP-3000 etc.
                        Boost Bits

                  A server is also a computer that provides data and other services to other computers. It is
                  used in offices where many computers are connected to each other.



                 Mainframe Computers

                 Mainframe computers are very huge, fast, powerful
                 and more expensive than minicomputers. They
                 often have multiple microprocessors and can be
                 so large that they occupy an entire room. These
                 computers are used in large organisations that
                 handle  vast  amounts  of  data,  like  banks.  For
                 example,  IBM zSeries, IBM 4381, ICL 39, etc.



                                                              Supercomputers

                                                              Supercomputers are  the largest and fastest type
                                                              of computers.  Some are  so big that  they occupy
                                                              an  entire  floor  of  a  building  and  are  extremely

                                                              costly. They can  handle massive  amounts of data
                                                              at  high speeds. Supercomputers  are  used by large
                                                              organisations and government agencies for complex
                                                              tasks like weather forecasting and rocket launches.

                 examples include China’s Tianhe-2, Japan’s Fugaku, and IBM’s Summit and Frontier, which
                 are crucial for advancing fields such as artificial intelligence, big data analytics, and scientific
                 research.
