                      LIMITATIONS OF A COMPUTER

                  Computer is a versatile machine and performs multiple functions, but it has the

                  following limitations:
                          Lack of decision-making ability: A computer does not  have a brain like
                        human beings. It cannot take a decision on its own. It can only perform the
                        tasks that are instructed by the human being.
                          Lack of intelligence: A computer is not gifted with intelligence as human
                        beings are. It can only work as per the instructions given by human beings.

                          Lack of feelings and emotions: Computers are different from human beings.
                        It does not possess feelings and emotions like human beings. It cannot do
                        anything on its own.
                          Time taken in planning and programming: We have to first choose the jobs

                        to be computerised, and then proper planning and development of programs
                        can take days, months and sometimes even years.

                      WORKING OF A COMPUTER

                  A commonly used computer needs the
                  following hardware to work:

                      ✶  Input devices
                      ✶  Output devices

                      ✶  Storage devices

                      ✶  CPU (Processing device)
                  Along with the hardware,  the computer  requires

                  software to work. A set of instructions written in
                  any  computer  language  is known  as a  program.
                  Programs are stored in the computer’s memory.
