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: -The second-generation series of computers from IBM saw approximately six times higher computational speed than computers developed using vacuum tubes in the first generation. In particular, the IBM 7090 was built using over 50, 000 transistors, and extremely fast magnetic cores.
Detailed explanation-4: -The second-generation computers emerged with the development of Transistors. The transistor was invented in 1947 by three scientists J. Bardeen, W.H Brattain and W. Shockley.
