The Five Generations of Computers were all not exact and some overlap in technologies exist. And all of the 5 generations of computers are sometimes useful in providing a general perspective of some of the advancements in computing technology.

The first generation of electronic computers were those implemented using vacuum tubes.
generations of computersThere are actually FIVE generations of computers.The first generation of electronic computers were made of vacuum tubes and they were big as a room.

5 Generation of Evolution of computers:1. First Generation (1940-1956) Vacuum Tubes2. Second Generation (1956-1963) Transistors3. Third Generation (1964-1971) Integrated Circuits4. Fourth Generation (1971-Present) Microprocessors5. Fifth Generation (Present and Beyond)ArtificialIntelligence.

Pictures of the five generations of computers are not as easy to find as one might think. The best way to find them is to use a search engine and type in "(first, second…one at a time) generation of computers." Though some of the ad pictures at the bottom of the page might be offensive to some, the best pictures found for the first generation are at the Related Link. The second generation brought us computers very much like the PCs we have today, and from that point, the main progress was made with internal changes, though other changes, like LCD monitors, laptops, cell phones, etc. came about, too. Pictures of each generation can be found on websites linked at the Related Links.
