Following are the limitations of computers:
                      No IQ (Intelligence Quotient): It works only on the instructions provided by humans.

                      Lack of decision-making ability: A computer cannot make decisions on its own. It
                      depends on the input provided by humans and may give inaccurate results when an
                      unexpected situation arises.
                      No Common Sense: Computers cannot learn from their previous mistakes. Therefore,

                      we have to provide accurate data in order to get accurate results.

                    ▶  In earlier times, people used bones, stones, and pebbles to count and calculate.
                    ▶  China invented the first calculating device called the abacus.
                    ▶  John Napier created a manually-operated calculating device in 1617, called Napier's Bones.
                    ▶  Pascaline calculator is the first mathematical calculator in the world.
                    ▶  Charles Babbage developed the Difference Engine in 1822 and Analytical Engine in 1837.
                    ▶  The first-generation computers used vacuum tubes.
                    ▶  The second-generation computers replaced vacuum tubes with transistors.
                    ▶  The third-generation computers included integrated circuits (ICs).
                    ▶  The fourth-generation computers used microprocessors.
                    ▶  The distinct feature of the fifth-generation computers is the introduction of artificial intelligence.
