In which generation of computers, “Integrated Circuit” was introduced?
In which generation of computers, “Integrated Circuit” was introduced?
- The third generation of computers, covering the years 1964 to 1971, was the breakthrough for integrated circuits. Instead of having separate transistors on separate circuit boards, engineers found a way to put many, many transistors, resistors, and capacitors on a single silicon chip. This revolutionized the size, cost, speed, and reliability of computers. A good example of the third generation computers was IBM's System/360.
- First Generation: This generation (1940s–1956) relied on bulky vacuum tubes for circuitry, which were prone to failure and generated intense heat.
- Second Generation: This generation (1956–1963) saw the replacement of vacuum tubes with transistors, making computers smaller and faster, but they still used discrete components rather than integrated ones.
- Fourth Generation: This generation (1971–Present) is defined by the microprocessor, which uses Large Scale Integration (LSI) or Very Large Scale Integration (VLSI) to fit thousands of integrated circuits onto a single silicon chip.
