GENERATION OF COMPUTERS

Third (3rd) Generation of Computer (1964-1971)

These are computers produced from 1964-1971. It is based on Integrated Circuits (ICs). It supported remote time-sharing, processing, and multi-programming operating system. It used Large magnetic core, magnetic tape/disk.

Some of the High Level languages used are:

  1. FORTRAN-II ii. COBOL iii. PASCAL PL/1
  2. BASIC v. ALGOL-68, etc

Examples are;
