Detailed explanation-1: -The correct answer is Second. Second Generation(1955-1964): The computer made in the second generation was completely based upon transistors. Transistors replaced vacuum tubes in computers.
Detailed explanation-2: -In this generation, assembly language and high-level programming languages like FORTRAN, COBOL were used. The computers used batch processing and multiprogramming operating system.
Detailed explanation-3: -It was invented at Bell Labs jointly by three individuals, William Shockley, Walter Houser Brattain, and John Bardeen in 1947. Unlike the first generation computers, the computers in the second generation used assembly language instead of binary machine language. This allowed developers to input instructions in words.
Detailed explanation-4: -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.
