Not only this, they were expensive to run, used a lot of electricity, and were limited to what they could do – they certainly couldn’t multitask, that was for sure.
These were widely used in the first computer systems for circuitry, while magnetic drums were used for memory.Īs you’re most likely aware, these first computers were huge, and would quite often take up an entire room. First Generation (1940-1956)Įverything started with vacuum tubes. The first generation began in the 1940s and they go all the way up through today. Experts say that there are five generations, which means there have been five-time periods during which computer science has taken a big leap in its technological development. Technology is just growing and growing, and when you think about the time that humans have been around, it’s really happened in such a minuscule time period.
