In which computer generation were transistors first introduced?
Show answer Hide answer
Answer: C. Second
Explanation
Transistors were first introduced during the second generation of computer hardware development history. These revolutionary semiconductor devices replaced bulky, unreliable vacuum tubes to amplify and switch electrical signals. Choosing second generation correctly matches the established technological timeline of computer engineering evolution. Second-generation computers spanned roughly from the late 1950s through the mid-1960s, driven by solid-state physics. Transistors consumed far less electrical power, generated minimal heat, and offered vastly superior operational reliability. The invention of the transistor allowed computers to become smaller, faster, and more commercially viable for businesses.
Understanding computer generations illustrates how material science breakthroughs directly fueled the digital revolution. Solid-state electronics paved the way for modern microprocessors, integrated circuits, and pocket-sized mobile devices. Historians view the transition to transistors as one of the most pivotal milestones in industrial technology history. Fourth generation computers are characterized by the advent of ultra-large-scale integration and powerful microprocessors. Third generation computers utilized integrated circuits containing numerous transistors etched onto single silicon chips. First generation computers relied entirely on fragile, power-hungry vacuum tubes for their internal circuit logic.
