Generations of Computers Flashcards
The use of vacuum tubes as a means of storing data in memory and the use of the store program concept.
First Generation (1946-1959)
The use of transistors, diodes, and magnetic storage, built-in error detecting device
Second Generation (1959 – 1965)
The use of integrated solid-state circuity improved secondary storage devices, and new input/output devices were the most important advantages.
Third Generation (1965 – 1971)
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.
Fourth Generation (1971 – 1980)
It was invented by Robert
Noyce and Jack Kilby In 1958-1959. It was a single component containing number of transistors.
Integrated Circuit (IC)
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.
microprocessor
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.
Fifth Generation (1980 – onwards)
This generation is based on ULSI(Ultra Large Scale
Integration) technology resulting in the production of microprocessor chips having ten
million electronic component.
Fifth Generation (1980 – onwards)
