Generations of Computers

Question 1

The use of vacuum tubes as a means of storing data in memory and the use of the store program concept.

Answer 1

First Generation (1946-1959)

Question 2

The use of transistors, diodes, and magnetic storage, built-in error detecting device

Answer 2

Second Generation (1959 – 1965)

Question 3

The use of integrated solid-state circuity improved secondary storage devices, and new input/output devices were the most important advantages.

Answer 3

Third Generation (1965 – 1971)

Question 4

The development of the different areas in computer technology such as:
multiprocessing, multiprogramming, miniaturation, time-sharing, operating speed and virtual
storage. This technology is based on Microprocessor.

Answer 4

Fourth Generation (1971 – 1980)

Question 5

It was invented by Robert

Noyce and Jack Kilby In 1958-1959. It was a single component containing number of transistors.

Answer 5

Integrated Circuit (IC)

Question 6

It is used in a computer for any logical and arithmetic function to be performed in any program. Graphics
User Interface (GUI) technology was exploited to offer more comfort to users.

Answer 6

microprocessor

Question 7

This generation is based on artificial intelligence. The aim of the this generation
is to make a device which could respond to natural language input and are capable of
learning and self-organization.

Answer 7

Fifth Generation (1980 – onwards)

Question 8

This generation is based on ULSI(Ultra Large Scale
Integration) technology resulting in the production of microprocessor chips having ten
million electronic component.

Answer 8

Fifth Generation (1980 – onwards)
