First Generation
• Vacuum tubes were used for circuitry.
• Magnetic drums were used for memory.
• The size of the early computers took up an entire room
![Page 15: History of Computer Wyatt Feiling Did you know... The first idea for a computer was in the early 1800s Charles Babbage is the man who is credited with.](https://reader038.fdocuments.us/reader038/viewer/2022103122/56649f4e5503460f94c6fcfb/html5/thumbnails/15.jpg)
Second Generation
• Transistors replaced vacuum tubes.• Were now smaller, faster, and more
efficient.

Fifth Generation
• Still in development• Will use parallel processing and
superconductors to create artificial intelligence.
• These new devices will be capable of learning.
