                      First Generation Computer   First Generation: 1946-1959 is the period of first-generation computer.  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:   ENIAC   EDVAC  UNIVAC   IBM-701   IBM-650 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 ...

  What is Computer? 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.
