Using or done by computers and digital technology; in a way that uses electronic devices and data.
From Latin 'digitus' meaning finger (because people counted on fingers). 'Digital' came first (1630s, meaning relating to fingers), then adapted to mean discrete numerical data in the 1940s with computers.
The word 'digit' for numbers comes from 'finger' because humans have 10 digits and counted in groups of 10—which is why our number system is base-10, and why 'digit' now means any computer number!
