Computing pre1950s FIRST ELECTRONIC COMPUTERS Very few electronic computers were built before the 1950s. However, in the late 1940s and early 1950s, scientists began working on a new kind of computer that would use vacuum tubes to process information. This was the beginning of the first electronic computers, which were much larger and more expensive than modern computers today. Over time, these machines evolved into smaller, faster, and more efficient devices that could be used by anyone with an education. Today, we have personal computers in our homes, schools, and workplaces, as well as mobile phones and tablets that can access the internet and perform tasks on the go. So, what's next for computer technology? Will it continue to evolve at a rapid pace, or will it stagnate and become less useful? Only time will tell. But one thing is certain: computer technology has come a long way since its humble beginnings in the 1940s.
