Understanding
Data Communications
2-Day Session

Afraid to ask how this all works, for fear that your peers will laugh at you? Concerned that your customers or peers know more about data than you do? These are common pitfalls in the Telecommunications industry. Everyone uses the day-to-day jargon regarding how computers work, how they send information from one location to another and what the protocols are all about.
