means The study of how to represent, process, and reason about information using algorithms and computation.

from Literally 'computer' + 'science' — but the twist is that 'computer' used to mean a *person*, specifically a human who computed: someone, often a woman, employed to carry out calculations by hand before machines took over the job. The word traces to Latin 'computare,' to reckon or sum up, from com- (together) + putare (to reckon, settle an account). Only in the 20th century did 'computer' slide from job title to machine, and 'computer science' emerged as its own discipline once people realized the machines needed a whole field devoted to understanding them.
