Every generation of computer experienced a major technological development that basically changed the way computers operate, thus resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices .The history of computer development is always referred to in reference to the different generations of computing devices.

The first generation (1940-1956) is the Vacuum Tubes. The first generation computers used vacuum tubes for circuitry and magnetic drums for their memory, and because of that they big and were often large, taking up entire rooms to build. They are so expensive to operate because they are very large and took a lot of maintenance and in addition they use a great deal of electricity and similarly to current computers problem they generated a lot of heat thus which was often are the root cause of malfunctions. The first generation computers relied on the machine language, the earliest and lowest-level of programming language understood by computer in order to perform operations, and they could only be solved for one problem at a time. The punched cards and the paper tape are basically used as the input, and then the output are displayed on the print out. The UNIVAC and ENIAC computers are good examples of the first-generation computing devices. The UNIVAC was the first commercial computer created and sold to a client that is, the U.S. Census Bureau in 1951.
