    SECOND GENERATION

                          Timeline: 1950s
                          Technology: Transistors
                          Example of Computer: UNIVAC III, IBM 1401, IBM
                          700 and Honeywell 200, etc.
                          Features:
                             More efficient and economical
                             Smaller in size compared to first-generation computers
                             Could calculate data in seconds

                                                           THIRD GENERATION

                          Timeline: 1960s

                          Technology: Integrated Circuits or ICs (An IC is also called
                          a chip, and it houses a large number of transistors in it.)
                          Example of Computer: IBM 360, Apple 1, UNIVAC 1108,
                          and UNIVAC AC 9000
                          Features:

                             Faster and more economical than second-generation computers
                             Highly reliable
                             The keyboard and the mouse were used for input purposes

                             Used an operating system, thereby allowing many applications to run at one
                            time

                                                          FOURTH GENERATION

                          Timeline: 1970s
                          Technology: Microprocessor (A Microprocessor is the
                          entire CPU on a single chip. It is a VLSI circuit. VLSI

                          stands for Very Large-scale Intergration).
                          Example  of Computer:  Desktop,  HP 9000, IMP PC,
                          Apple Macintosh

                          Features:
                             Reduction in the size of computer
                             More reliable than the earlier generation of computers with a great storage
                            device

                             Extremely powerful and can process millions of instructions per second

                                                                                      Techipedia (The Computer Timeline)  107
