FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.

Detailed explanation-2: -Fourth Generation Computers. After third-generation computers, which mostly utilized microprocessors, fourth-generation computers were released in 1972. VLSI technology, or Very Large Scale Integrated (VLSI) circuits, was employed in these computers.

Detailed explanation-3: -The Kenbak-1, released in early 1971, is considered by the Computer History Museum to be the world’s first personal computer. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971.

Detailed explanation-4: -3. Third Generation of Computers(1964 – 1971): Jack Kilby invented the Integrated Circuit. This Integrated Circuit replaced the use of transistors in the third generation of computers.

Detailed explanation-5: -At the beginning of the 1970s there were essentially two types of computers. There were room-sized mainframes, costing hundreds of thousands of dollars, that were built one at a time by companies such as IBM and CDC.
