Webster’s New World Telecom Dictionary, by Ray Horak, is a comprehensive telecommunications dictionary of more than 7,500 terms critical to understanding voice, data, video, and multimedia communications system and network technologies, applications, and regulation. Given the convergence of computing and communications, the book also effectively is a computer dictionary with a telecom focus. It is thoroughly researched, highly objective, absolutely accurate, and includes just about every essential term, abbreviation, acronym, contraction, initialism, and portmanteau you might encounter in the telecom and datacom domains. Although the book is a technical dictionary, Horak’s plain-English, commonsense style yields definitions that are as thoroughly understandable to the business professional or student as they are to the electrical engineer. In fact, many entries are encyclopedic in nature, discussing applications and issues. Horak also injects a bit of his wry sense of humor, sprinkling occasional telecom trivia and marginally related definitions that will have you smiling and chuckling to yourself, but not to the point that they detract from what is an important book on a serious subject. An instant classic, Webster’s New World Telecom Dictionary is the one and only telecom dictionary you will need. It also makes a perfect companion to Horak’s Telecommunications and Data Communications Handbook, published by Wiley-Interscience in October 2007.
