Detailed explanation-1: -History of Computers: 2nd Generation. By 1948, the invention of the transistor drastically changed the computer’s development. The transistor replaced the cumbersome vacuum tube in televisions, radios and computers.
Detailed explanation-2: -Examples of the second generation computers include IBM 1620, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108. As a result, they worked on AC and therefore were faster than their predecessors.
Detailed explanation-3: -Physicist Walter Brattain shared the 1956 Nobel Prize with William Shockley and John Bardeen for jointly inventing the transistor, a device that replaced the bulky and fragile vacuum tube in electronic equipment.
Detailed explanation-4: -Transistors transformed the world of electronics and had a huge impact on computer design. Transistors made of semiconductors replaced tubes in the construction of computers. By replacing bulky and unreliable vacuum tubes with transistors, computers could now perform the same functions, using less power and space.
Detailed explanation-5: -The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit).
