What is Transistor computer?
[[File:IBM 1620 data processing machine on display, Seattle World's Fair, 1962.jpg|right|thumb|IBM 1620, a transistor computer used in 1960s]] A '''transistor computer''', now often called a '''second generation computer''',<ref>{{cite book|last1=Morleey|first1=Deborah|title=Computers and Technology in a Changing Society|date=2004|publisher=Thomson/Course Technology|isbn=9780619267674|page=6|url=https://books.google.com/books?id=qrIHJPj88gAC|access-date=Dec 29, 2017}}</ref> is a [[computer]] which uses individual [[transistor]]s instead of [[vacuum tube]]s. The first generation of electronic computers used vacuum tubes, which were big, unreliable, and generated large amounts of heat. A second generation of computers, through the late 1950s and 1960s contained [[circuit board]]s filled with individual transistors and [[magnetic core memory]]. These machines were in use up to the late 1960s, when [[integrated circuits]] became available. ==References== {{reflist}} [[Category:Historical computers]]
