Which generation of computing is known for first using keyboards and monitors?

The second generation of computers primarily utilized transistors instead of vacuum tubes, leading to smaller and more efficient machines. However, this generation relied heavily on punched cards and printouts for input and output, rather than the more interactive keyboards and monitors that became prevalent in the third generation.

The fourth generation of computing is defined by the emergence of microprocessors and personal computers, further advancing user interfaces and capabilities. While keyboards and monitors were already in use by this time, they were not the first generation to employ them; hence, this option is incorrect.

The fifth generation focuses on artificial intelligence and advanced computing technologies, including natural language processing and robotics. Although keyboards and monitors continued to be used, they do not represent the first generation to adopt these devices in computing.
