Telecom 101 covers telecom, datacom and networking from A-Z, organized in logical chapters covering all major topics, and written in our signature telecom for non-engineers style. Specifically designed for the non-engineering professional, we’ll bust the buzzwords, demystify the jargon, and cut through doubletalk. We fill in the gaps, build a solid, structured base of knowledge and show how everything fits together... knowledge and understanding that lasts a lifetime. This content, tuned and refined over the course of eighteen years, has been taught to thousands of people needing to build a solid, structured understanding of telecom, datacom and networking. A high percentage of seminar attendees specifically praise the course materials on seminar evaluations – materials now available in softcover textbook format in Telecom 101. Teracom’s Telecom 101 is an invaluable day-to-day handbook, and is used by many as an economical and convenient way to self-study. A US Army communications specialist deployed to Iraq called it “a lifesaver” when contacting to us to order his own copy after the owner of the one he was borrowing demanded it back! The third edition, published 2008, is completely revised and updated, with complete coverage of telecom, datacom, IP and networking fundamentals plus up-to-date information on VoIP, MPLS, IP, DSL, wireless and more.
