                 The UNIVAC had 5,200 vacuum tubes.


                    Features of First Generation Computers


                        Huge in size.
                        Very expensive.

                        Made up of vacuum tubes.
                                                                                          Vacuum tube

                      Second Generation (1950s)

                 After  1955,  use  of  transistors and  magnetic  tapes
                 changed the image of the electronic computer.

                 During this period, the major computer manufacturers
                 began  to  offer a range of accessories  such as:  Page
                 Printers, Cathode Ray-Tube display, Card Feeders, etc.                      Magnetic tape



                                      Features of Second Generation Computers

                                        Made up of transistors.

                                        Magnetic tapes were used to store data.

                                        Small in size and less expensive than the first generation computer.
                                        Faster and reliable.
