2. Brief Overview of the History of Computers

Analog computers, such as the abacus and tally mark, have been around since ancient times. Those and other analogous computers throughout history, such as the slide rule and nomogram, certainly furthered the logic that forms the basis for current computer models and, as such, should be mentioned in any discussion of the history of computers. For our purposes here, though, we will only be looking at the history of computers since the first mechanical computer was developed, in the 19th century.
