Network activation will activate a plug-in for every site in a network whereas regular activation will only activate a plug-in for the site you’re currently on. As far as implementation goes, there is one other important difference:

If your plug-in is built to do something when it’s activated (via register_activation_hook()), this will fire automatically when you activate a plug-in normally, but it will not fire for a network-activated plug-in until you visit the admin screen for each blog.

So if major database updates are tied in to register_activation_hook() they won’t occur until you log in to the other sites.
