Yes, terminal means “end” or similar. Eg. “Terminal cancer”, “the airport terminal” etc. same root word as"terminate"

Computer terminal is literally called a terminal because it’s the thing on the user side end of the long long wire that starts from the big big computer.

One of those things that make a lot more sense if you think hard of the history.

Unless terminal is another word for final station.

It is. Also terminus, terminal (cancer), and so on, all relating to finality or end.
