TELECOMMUNICATION NETWORKING
A telecommunications network is a collection of nodes and links that is capable of carrying audio, visual, and data communications. While the term was once used to refer only to the collection of switches and wiring used by telephone service providers to provide audio connectivity to residential and business customers, it is now understood to include Internet, microwave, and wireless equipment as well as the more traditional forms of telephony. There are several different classes of telecommunication networks, with each of them having a slightly different focus.
The main function of any telecommunications network is to provide efficient transmission of information from a point of origin to a point of termination. A telephone call is the easiest way to understand the function. A call is initiated at a given point, with the signal routed through a series of nodes that may involve a combination of wired switches, Internet relays, and wireless nodes. The signal eventually terminates at a local switch, where is it then routed to the equipment used by the intended recipient. This process takes place within seconds, and establishes a connection that allows the parties to interact in a real-time fashion.
Today, there are several basic types of telecommunications networks in use. Along with the PSTA, or public switched telephone network, that most people are familiar with, there is also the Internet, a medium that is increasingly used for both voice and visual communications. Private computer networks are a common tool in many businesses today, as well as many institutions of higher learning. These basic types are all classified into several categories, which include such options as wide area networks, local area networks, and virtual private networks.
