UNIVAC

                 In 1951,  John Mauchly  and  Presper Eckert  invented the  Universal Automatic

                 Computer (UNIVAC). This successful invention could handle both numbers and
                 text. The UNIVAC used 5,200 vacuum tubes. It had a magnetic tape storage system
                 for data, which was a new technology at the time.

                 Second Generation (1950s)

                 Second-generation computers, which emerged in

                 the late 1950s and early 1960s, marked a significant
                 advancement from the first generation. They replaced
                 vacuum tubes with transistors that make computers

                 smaller, faster, and more reliable in comparison to
                 first-generation computers. These computers used magnetic tapes that offer greater
                 storage capacity.

                 During this time, major computer manufacturers started offering various accessories
                 like Page Printers, Cathode Ray Tube displays, Card Feeders, etc.
