"Generations of Computer"

  "Source : https://www.gearpetrol.com/tech/a392118/best-apple-desk-setup/"           In the fifth generation, the VLSI technology became ULSI (Ultra Large Scale Integration) technology, resulting in the production of microprocessor chips having ten million electronic components. This generation is based on parallel processing hardware and AI (Artificial Intelligence) software.  AI is an emerging branch in computer science, which interprets means and method of making computers think like human beings.  All the Higher level languages like C and C++, Java, .Net etc. are used in this generation.   AI includes: • Robotics  • Neural networks  • Game Playing  • Development of expert systems to make decisions in real life situations.  • Natural language understanding and generation.

VLSI circuits having about 5000 transistors and other circuit elements and their associated circuits on a single chip made it possible to have microcomputers of fourth generation. Fourth Generation computers became more powerful, compact, reliable, and affordable. As a result, it gave rise to personal computer (PC) revolution. In this generation Time sharing, Real time, Networks, Distributed Operating System were used. All the Higher level languages like C and C++, DBASE etc. were used in this generation. READ MORE

  "Source : https://tutsmaster.org/disadvantages-of-third-generation-computer-2/"                          The third generation of computer is marked by the use of Integrated Circuits (IC's) in place of transistors. A single I.C has many transistors, resistors and capacitors along with the associated circuitry. The I.C was invented by Jack Kilby. This development made computers smaller in size, reliable and efficient. In this generation Remote processing, Time-sharing, Real-time, Multi-programming Operating System were used. High level language (FORTRAN-II TO IV, COBOL, PASCAL PL/1, BASIC, ALGOL-68 etc.) were used during this generation. READ MORE

                                     A transistor computer, now often called a second generation computer is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable. A second generation computer, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third generation computer.  The University of Manchester's experimental Transistor Computer was first operational in November 1953 and it is widely believed to be the first transistor computer to come into operation anywhere in the world. There were two versions of the Transistor Computer, the p...

            A vacuum-tube based computer now termed as the First generation of computer, is a computer that uses Vacuum-tube, for logic circuitry. Vacuum-tube computers, continued to be build into the 1960s. Vacuum-tube technology requires a great deal of electricity. The ENIAC   computer(1946) had over 17,000. In operation ENIAC consumed 150 kilowatts of power, of which 80 kilowatts were used to for heating tubes, 45 kilowatts of DC power supply, 20 kilowatts of ventilation blowers and 5 kilowatts for Punched-card.

What means by Generations of Computer?      Generation in computer terminology is a change in technology a computer is/was being used. Initially, the generation term was used to distinguish between varying hardware technologies.           There are five generations of computers known till date. Each generation has been discussed in detail along with their time period and characteristics.
