                                     OUR COMPUTER GENRATION



Introduction: 
A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data.
Nowadays, a computer can be used to type documents, send email, play games, and browse the Web. It can also be used to edit or create spreadsheets, presentations, and even videos. But the evolution of this complex system started around 1946 with the first Generation of Computer and evolving ever since.
There are five generations of computers.

  1. FIRST GENERATION

    • Introduction:
      1. 1946-1959 is the period of first generation computer.
      2. J.P.Eckert and J.W.Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated And Calculator”.
    • Few Examples are:

      5. IBM-650
        6. …
    • Advantages:
      1. It made use of vacuum tubes which are the only electronic component available during those days.
      2. These computers could calculate in milliseconds.
    • Disadvantages:
      1. These were very big in size, weight was about 30 tones.
      2. These computers were based on vacuum tubes.
      3. These computers were very costly.
      4. It could store only a small amount of information due to the presence of magnetic drums.
      5. As the invention of first generation computers involves vacuum tubes, so another disadvantage of these computers was, vacuum tubes require a large cooling system.
      6. Very less work efficiency.
      7. Limited programming capabilities and punch cards were used to take inputs.
      8. Large amount of energy consumption.
      9. Not reliable and constant maintenance is required
