                     LIMITATIONS OF A COMPUTER

                     A 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 has

                       zero intelligence. 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.

                        Human Dependency: A computer is a machine that is fully automated once switched on.
                       But it cannot work to switch itself on. It cannot work completely on its own without human
                       assistance.

                                                                                                  Computer Timeline    27
