Computer History

Some people find it difficult to exist without computers of one kind or another. They may even believe they always existed. Others tell you they have only been in use for the last two or three decades. Neither is right. Computers and computing have been used for centuries, though not in their present form. An abacus is a manual computer, punch card machines used a form of computing at the beginning of the 1800s, Babbage built a type of computerised machine in the early 1800s and ENIAC was created in 1945.
