How computer are used in air traffic control?

Now days with the more extended use of electronic data strips in the enroute and terminal environments, and the use of radar systems, computers are very extensively used. If you go inside of one of the 20 or so ARTCCs (air route traffic control centers) in the U.S., you will find that all of the radars are essentially computers hooked up to a large network served by a few master servers that are connected to another network on radars and communication equipment.

Also, there are various programs used for grabbing weather, NOTAMs, SOPs, LOAs, etc.
