This course begins with a comprehensive look at the various technologies used to connect computers to the Internet, such as analog modems, ISDN, and DSL. We then examine the infrastructure of Internet providers so that students can understand how it all “hangs together”. We look at the costs, speeds and bandwidths of the various access methods. We look at the difference between analog and digital communication, and learn how modems work. We discuss how high-speed transmission is accomplished using fiber-optic cable. The course culminates in a visit to a local Internet provider to see the Internet from their perspective.
