COMPUTER FUNDAMENTALS

Detailed explanation-1: -A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.

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

Detailed explanation-3: -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-4: -The bipolar transistor was invented in 1947. From 1955 onwards transistors replaced vacuum tubes in computer designs, giving rise to the “second generation” of computers.
