The first generation of computer

The major piece of technology for the first generation computers was vacuum tubes. From 1940 through 1956, vacuum tubes were widely used in computers.

These tubes were large components and they resulted in first generation computers. These computers were very large in size. They used to take a lot of space in the room. Some computers even took up an entire room.

A great example of first generation computer is ENIAC. It consisted of:

  • 20,000 VACUUM TUBES
  • 10,000 CAPACITORS
  • 70,000 RESISTERS

Its weight was over 30 tons and a large space was required to place this computer. Some other examples of first generation computers are EDSAC, Manchester Mark 1, and IBM 701.

Advantages of first generation computers:

First generation computer was not so useful. But some of advantages are here

  • It used vacuum tubes. These were the only electronic components available in those days.
  • These computers had the ability to calculate in milliseconds.

Disadvantages of first generation computers:

There were many disadvantages. Some of given below.

  • They were very big in size.
  • The weight was about 30 tons.
  • They were costly.
  • They were based on vacuum tubes.
  • They could store a small amount of information.
  • They required a large cooling system.
  • The efficiency of work was less.
  • Push cards were used for input.
  • They had limited programming capabilities.
  • A large amount of consumption of energy.
  • They were not reliable.
  • Constant maintenance was required.
