Detailed explanation-1: -The transistor was at work in the computer by 1956. Along with early advances in magnetic-core memory, transistors led to second generation computers that were smaller, faster, more reliable and more energy-efficient than their predecessors.
Detailed explanation-2: -When computer technology became more popular in the late 1950s and 1960s, the second generation of computers, which replaced vacuum tubes with transistors, was developed. Transistors, rather than vacuum tubes, were used exclusively in the second generation of computers.
Detailed explanation-3: -The first transistorised computer was built at the University of Manchester and was operational by 1953; a second version was completed there in April 1955. The later machine used 200 transistors and 1, 300 solid-state diodesand had a power consumption of 150 watts.
Detailed explanation-4: -2nd generation computers had transistors instead of vacuum tubes.
