Computers have evolved over the years through several generations, each marked by significant advancements in technology and capabilities. Here are the five generations of computers:

First Generation (1940s-1950s): Used vacuum tubes, large and slow.

Second Generation (1950s-1960s): Employed transistors, smaller and more reliable.

Third Generation (1960s-1970s): Integrated circuits, faster and cheaper.

Fourth Generation (1970s-Present): Microprocessors, personal computers, GUIs.

Fifth Generation (Present and Beyond): AI, quantum computing, cloud computing, and advanced technologies.
