What Are The Generations Of A Computer?
First Generation Computer: The beginning of the commercial computer age is from UNIVAC (Universal Automatic Computer). It was developed by the Census department of the United States and developed by two scientists Mauchly and Echert in 1947. First generation computers were used during 1942-1955. They were based on vacuum tube, which was a glass (tube) that controlled and amplified the electronic signals. Second Generation Computer: Three scientists of Bell laboratories – J. Baardeen, H.W. Brattain and W. Shockley – developed transistor in 1948. Transistor is a small device that transfers electronic signals across a resistor. The transistor was used in computer by 1956 in second generation computers. Third Generation Computer: Jack Kilby developed the integrated circuit (IC) in 1958. An IC combined three electronic components onto a small silicon disc. Scientists later manage to fit even more components on a single chip called “semiconductor”. Computers became ever smaller as a result.
