COMPUTER FUNDAMENTALS

Detailed explanation-1: -The period of second generation was from 1959-1965. In this generation, transistors were used that were cheaper, consumed less power, more compact in size, more reliable and faster than the first generation machines made of vacuum tubes.

Detailed explanation-2: -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-3: -2nd generation computers had transistors instead of vacuum tubes.
