I don't go to USITT every year, but I'm going this year and will be presenting a session on basic computer networking on March 26 2014, from 2:30PM - 4:00PM. Here's the session description:
John Huntington, author of Show Networks and Control Systems, introduces networks and their applications for shows. Key protocols such TCP/UDP/IP will be introduced, and some basic network topology issues will be covered. Key aspects of network operation will be demonstrated.
I hope to see you there!
