                   disadvantages like limited upgradability, expensive, overheating, battery life degradation and
                   small screen size.

                 •   Tablet: It is a portable digital computer that is smaller than a laptop
                   computer. It has a touchscreen as its primary input device instead of a
                   mouse. Similar to a laptop, the tablet computer also has a rechargeable

                 Minicomputer

                 A minicomputer, also known as "mini", is a type of computer that is
                 bigger, more expensive, and more powerful than a microcomputer.
                 It is bigger in size and faster in processing speed. It can contain one
                 or more microprocessors as its processing units. It is mainly used for
                 scientific and engineering computations. It has the capability to serve
                 a number of users and run multiple programs simultaneously. It is also
                 known as a small or midsized server computer. It can support several
                 users working at the same time on the same machine which means
                 it  supports  a  multi-user  environment.  Some  common  examples  of
                 minicomputers are PDP-11, PDP-8, HP-3000, etc.
