The third generation

The third generation of computers emerged during the mid-1960s and were based upon integrated circuit technology. Integrated circuits provided significant reduction in size over transistors. Minicomputers evolved from integrated circuit technology. These were smaller and cheaper than mainframes but delivered similar processor power, although were often of lower storage capacities. Minicomputers became affordable systems and were purchased in large numbers by organisations such as universities and other higher education institutes, as well as industrial, commercial and government organisations. Examples of systems that were built during this time were:

♦ The DEC PDP 8 minicomputer - this was a very popular computer system during the 1970s and provided multi-tasking facilities that enabled several people to use the system at the same time.

♦ The DEC PDP 11 - this was an even more popular minicomputer than the DEC PDP 8.
