Brief notes on Computer Revolution or Generation of Computers.
Second generation computers also saw a change in the way data was stored. Punched cards were replaced by magnetic tape and high speed reel-to-reel tape machines. Using magnetic tape gave computers the ability to read (access) and write (store) data quickly and reliably. Third Generation Computers.
The computers developed during the period 1965-70 are branded as the third generation computers. The significant features of these computers was that they were built with monolithic integrated circuits, (IC) each of which consisted of thousands of transistors and other electronic components on a single crystal.
Second generation operated using transistors. Third is known for using integrated circuits. Fourth required the use of microprocessors. The most recent fifth generation relies on the use of artificial intelligence, or AI. Without further ado, here is the list of generation of computer 1st to 5th. Enjoy! First generation of computer.
The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.
Third Generation Computer (1964 to 1975) Now another new technology named integrated circuits that is ICs came into existence and therefore the third generation computer was also came into existence. The third generation computers used the integrated circuits (ICs). Jack kilby developed the concept of integrated circuits in 1958.
The Third Generation (1965-1980) By the late 1960's operating systems designers were able to develop the system of multiprogramming in which a computer program will be able to perform multiple jobs at the same time.The introduction of multiprogramming was a major part in the development of operating systems because it allowed a CPU to be busy nearly 100 percent of the time that it was in.
First Generation of mordern computer (1946 - 1954) The period of first generation was 1946 - 1954. Computers of first generation used vacuum tubes as the basic components for memory and circuitry for Central Processing Unit.The first electronic computer, ENIAC (Electronic Numerical Integrator and calculator) was developed in 1947 at the University of Pennsylvania, USA.
