Features of Third Generation Computers:

                    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 its first line of desktop
                                                                       Microprocessor
                 PC, which used the Intel 8088 chip as                                                 IBM PC
                 the CPU. In 1983, IBM introduced the PC-XT, that had more memory and hard

                 drive space. In 1985, Microsoft released the first version of Microsoft Windows.

                 Features of Fourth Generation Computers:
                    VLSI called microprocessors were invented.

                    They were in size and could be placed on an office table.
                    They had a hard disk to store data.

                    Led to the introduction of GUI operating system.

                   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, that were designed to improve game and

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

                 Features of Fifth Generation Computers:

                     Will use artificial intelligence.
                     Improved size, cost, speed and performance.

                     New versions of GUI operating systems are being developed.
