It was the period from 1940 to 1956. They used magnetic drums for the memory. We can talk about a second generation from 1956 to 1963. Transistors replaced the vacuum tubes. This allowed computers to work in a faster way. A magnetic core replaced the drum. The computer had a longer useful life. The third generation appeared from 1964 to 1971.
