                 Features of Third Generation Computer
                    These computers were made of ICs.


                    The use of the ICs reduced the size and increased the speed of the computers.

                    They were more affordable and dependable.



                 Fourth Generation (1970s)
                 In 1980’s, Very Large Scale Integration

                 (VLSI)  came  into  existence  in  which
                 thousands of transistors were placed on
                 a single chip called microprocessor.

                 IBM  released  their  first  line  of  desktop
                 PC, which was used by the Intel 8088 chip              Microprocessor
                 as their CPU. In 1983, IBM introduced the                                             IBM PC
                 PC-XT, which had more memory and more hard drive space. In 1985, Microsoft released

                 the first version of Microsoft Windows.

                     Intel introduced the Intel 4004, the first microprocessor in 1971.







                 Fifth Generation (Present)

                 After 1986, VLSI technology was used to develop more powerful
                 microprocessors to improve the speed, size, cost and performance
                 of computers. In 1997, Intel introduced the MMX microprocessors,
                 which  were designed  to improve game and multimedia

                 performance. Scientists are still trying to develop computers with
                 Artificial Intelligence (AI).
