Quick illustrative example

Imagine an airport: you walk into the terminal building to catch your flight (transport meaning), you might use a laptop terminal window to run commands on a remote server while waiting (computing meaning), and in a news article you might read about someone with a terminal illness (medical meaning), all using the same underlying idea of an “end point” or “final stage.”
