3. the third computer generation (1964-1971)-The third generation is marked by the appearance of the link circuit (integrated circuits-IC: Integrated Circuit). The integrated circuits of low density (SSI: Small Scale Integration) can contain several dozen components and the average density integrated (MSI: Medium Scale Integration) contains hundreds of components on integrated circuits. Multi-layer printed circuit boards, semiconductor memory appearance began to replace the memory by pinky from. Most computer programs and the operating system divides the time used.
