During which generation of computers was the microprocessor first introduced?

Explanation

The microprocessor marked the beginning of the fourth generation of computers by integrating thousands of circuits onto a single silicon chip. Unlike earlier generations where computers occupied entire rooms, the Intel 4004 chip, created in 1971, combined the CPU, memory, and input/output controls into one compact unit. This advancement led to more powerful, smaller computers, enabling networking and eventually the rise of the Internet. Additionally, the fourth generation introduced graphical user interfaces, the computer mouse, and portable devices.
