FUNDAMENTALS OF COMPUTER

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: -A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes.

Detailed explanation-3: -The first generation of computers used vacuum tubes; the second generation of computers used transistors; the third generation of computers used integrated circuits; and the fourth generation of computers used microprocessors.
