Chapter 14 gives you a view from 20,000 feet of the most popular ways to transfer data and helps you find the best fit for your data needs. Although the chapter couldn’t possibly break down data transfer methods to the molecular level (that’s a whole other book), it does identify the items you will need to have if you want to use the technology, and also gives you a sense of the types of charges you can expect to pay. Chapter 15 introduces you to the makeup, features, and benefits of VoIP (Voice over IP), the hottest technology in telecom today.
