The main features of first generation computers included vacuum tube technology, unreliability, support for only machine language, high costs, large size, need for AC power, slow input and output, and high electricity consumption. Some examples of first generation computers were ENIAC, EDVAC, UNIVAC, IBM-701, and IBM-650.

Integration) technology, resulting in the production of microprocessor chips having ten
million electronic components]](https://image.slidesharecdn.com/generationsofcomputerswithpreviousanimations-141126062147-conversion-gate02/85/Piyush-Generations-of-computers-B-J-S-14-320.jpg)
Piyush-Generations of computers (B.J.S.)
- 5. The main features of first generation are: •Vacuum tube technology •Unreliable •Supported machine language only •Very costly •Generated lot of heat •Slow input and output devices •Huge size •Need of A.C. •Non-portable •Consumed lot of electricity
- 6. UNIVAC Some computers of this generation were: •ENIAC •EDVAC •UNIVAC •IBM-701 •IBM-650
- 9. NOTE-The computers of third generation used integrated circuits (IC's) in place of transistors. A single IC has many transistors, resistors and capacitors along with the associated circuitry. The IC was invented by Jack Kilby.
- 11. NOTE- The computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements and their elements and their associated circuits on a single chip (made it possible to have microcomputers )of fourth generation, which are Microprocessors.
- 14. [NOTE- 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]
