Generation of computers
First generation (1940 - 1956) The first generation of computers used vacuum tubes as a major piece of technology. Vacuum tubes were widely used in computers from 1940 through 1956 . Vacuum tubes were larger components and resulted in first-generation computers being quite large in size, taking up a lot of space in a room. Some first-generation computers took up an entire room. The ENIAC (Electronic Numerical Integrator and Computer) is a great example of a first-generation computer. It consisted of nearly 20,000 vacuum tubes, 10,000 capacitors , and 70,000 resistors . It weighed over 30 tons and took up a lot of space, requiring a large room to house it. Other examples of first-generation computers include the EDSAC (Electronic Delay Storage Automatic Calculator), IBM 701 , and Manchester Mark 1 . Second generation (1956 - 1963) The second generation of computers saw the use of transistors instead of vacuum tubes. Transistors were widely used in computers from 1956 to 1963 . Tra
