Digital

From Conservapedia

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.

The name comes from the Latin term digit, which means "finger".
