But then from the wikipedia page.

The Online Etymology Dictionary states that the use of the term to mean "'calculating machine' (of any type) is from 1897.

The Online Etymology Dictionary indicates that the "modern use" of the term, to mean 'programmable digital electronic computer' dates from "1945 under this name

So computer is the correct term before 1945.

“Computer” remains today a word that means any computational device. Without any context, it’s safe to assume programmability, but that’s just a reasonable assumption and not a definition of the word computer. People are making fixed-function computers today, and @orbital-decay and I already gave examples of them here. I happen to work on fixed-function non-programmable hardware that is part of a widely used commodity processor today, a sub-core that does arbitrary amounts of computation without being instruction driven and can’t be used for general purpose computation.

If a computer is a machine that helps me compute, then I'd argue an electronic calculator fits the definition regardless of the century:

I'd be inclined, though, to exclude "non machine" counting tools such as an abacus.
