                     LIMITATIONS OF A COMPUTER


                  A computer is a versatile machine that can do many tasks, but it has some limitations:

                      Lack of Decision-Making Ability: Unlike humans, a computer does not have a
                     brain and cannot make decisions on its own. It can only perform tasks that are
                     instructed by human beings.

                      Lack of Intelligence: Computers do not have intelligence like humans. They work
                     only according to the instructions given to them.

                      Lack of Feelings and Emotions: Computers do not have feelings or emotions.
                     They are not capable of experiencing emotions.

                      No Creativity: Computers cannot be creative or come up with new ideas without
                     human input.
