What's a push notification?

What's the definition of a push notification? Is it strictly an iOS thing?

No, it's not an iOS thing. But the first iPhones didn't have them. So when Apple finally introduced them, it, of course, became a big deal.
In a nutshell: a push notification is when a minimised/background app alerts you on the homescreen or on the notification bar or via a little pop-up that a new event occured - a new email, a new DM, a finished download...
It varies from OS to OS.

Push notification is whereby notifications of messages/emails/etc are 'pushed' to you, providing an instant notification of arrival
Many phones and email apps 'get' the data, either manually by you opening up the app or by by a scheduled 'look' for any updates (or synchronise).
And no, it's not strictly an iOS thing. It's one of the big selling points of the Blackberry platform.
