Each generation lasted for a certain period of time and each gave us either a new and improved computer or an improvement to the existing computer.Ī programmable electronic device that performs mathematical calculations and logical operations, especially one that can process, store and retrieve large amounts of data very quickly. Generally speaking, computers can be classified into three generations. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. The computer as we know it today had its beginning with a 19th century english mathematics professor name Charles Babbage.
