                   MARK-I (The First Electro-Mechanical Powered Computer)
                   In 1944,  Prof.  Howard Aikens built  the  first electro-mechanical  computer  named
                   Mark-I. It used punched cards and a typewriter for input and output. Mark-I was
                   much more reliable than early electronic computers.

                   ENIAC—The First Electronic Computer
                   Electronic  Numerical  Integrator  And  Computer,  was the first electronic  general
                   purpose  digital  computer built  in 1946  by  John  Mauchly and  Presper  Eckert. It

                   contained over 18,000 vacuum tubes and was 1000 times faster than Mark-I. ENIAC
                   consumed almost 200 kW of power.
