Description

Data networks are telecommunications networks installed and operated for information exchange between data communication devices such as computers. Because of the dramatic changes that have occurred to Data Networks, such as high-speed data and evolving Ethernet technology, almost all professionals in the datacom and telephone industries have been impacted. These new data networking products and services that are being introduced into the marketplace have advanced features and services that will enhance or replace ineffective or outdated systems. This excerpted chapter from Telecom Made Simple explains many fundamentals of data networks, including: Local area networks (LAN), the Internet, data terminals, network access control, protocols, other types of networks, networking devices, data communications systems, phoneline networking, and data network services. Low speed and high-speed data networks are also explained along with upcoming enhancements.
