Evolution of Computers through Generations

Computers have come a long way since their inception, with each generation bringing significant advancements in terms of technology, size, and processing power. Let’s take a journey through the different generations of computers:

First Generation (1940s-1950s)

The first-generation computers were colossal and used vacuum tubes for processing. They were extremely bulky, consumed massive amounts of electricity, and generated substantial heat. Some notable examples from this era include the ENIAC (Electronic Numerical Integrator and Computer) and UNIVAC (Universal Automatic Computer). They were mainly used for numerical calculations and were primarily found in research institutions and government agencies.
