A digital system is a mathematical system in which numbers shift between discrete states instead of rotating continuously. E.g., an abacus was a digital calculator because in it a bead had to be all the way up or all the way down, there was no meaning for a bead partially up or down. Electronic calculators and modern computers are also examples of digital systems. There is a form of [[mathematics]] called discrete mathematics which applies digital mathematics to technology as opposed to the traditional method of using analog mathematics.

A '''digital''' system is a mathematical system in which numbers shift between discrete states instead of rotating continuously. E.g., an [[abacus]] was a digital [[calculator]] because in it a bead had to be all the way up or all the way down, there was no meaning for a bead partially up or down. Electronic calculators and modern [[computer]]s are also examples of digital systems. There is a form of [[mathematics]] called discrete mathematics which applies digital mathematics to technology as opposed to the traditional method of using [[analog]] mathematics.
