Detailed explanation-1: -A second-generation computer, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic-core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation computer.
Detailed explanation-2: -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-3: -The correct answer is Second. Second Generation(1955-1964): The computer made in the second generation was completely based upon transistors.
