What strategy is used to keep programs automagically up-to-date? I'm talking about programs like Chrome, Firefox, etc., that can notify you if there is an update available and then install the new update for you.

My guess:

The program, once started, checks an Internet resource and simply compares its version ID with the latest version ID as published at the Internet resource. If they're different, notify the user or perform the update.

How are patches automagically applied in cases like this where the program to be patched is running? Does it close itself after spawning a separate updater program?

Thanks!
