A telecommunication network is a network of telecommunications links and nodes arranged so that messages may be passed from one part of the network to another over multiple links and through various nodes. Telecommunications network links (including their endpoints or "nodes") may in turn be built out of hierarchical transmission systems.

Examples of telecommunications networks are:
  • 1) Computer Network
  • 2) The Internet Network- The internet network is a global ‘network of networks’. The Internet is     connected via an Internet Service Provider (ISP) and then becomes part of a network. This network     then connects to a larger corporate network that interconnects with several other similar networks     through Network Access Points.
  • 3) The Public switched telephone network.
  • 4) The Global telex network.
  • 5) The Aeronautical ACARS network
Telecommunication Network Components

All telecommunication networks are made up of five basic components that are present in each network environment regardless of type or use. These basic components include terminals, telecommunications processors, telecommunications channels, computers, and telecommunications control software.
  • 1) Terminals are the starting and stopping points in any telecommunication network environment. Any input or output device that is used to     transmit or receive data can be classified as a terminal component.
  • 2) Telecommunications Processors are support data transmission and reception between terminals and computers by providing a variety of     control and support functions.
  • 3) Telecommunications Channels are the way by which data is transmitted and received. Telecommunication channels are created through a     variety of media of which the most popular include copper wires and coaxial cables. Fiber-optic cables are increasingly used to bring faster     and more robust connections to businesses and homes.
  • 4) In a Telecommunication environment computers are connected through media to perform their communication assignments.
  • 5) Telecommunications Control software is present on all networked computers and is responsible for controlling network activities and     functionality.
Types of Telecommunication Networks

In its most basic form a network is an interconnected system of things or people. From a technical standpoint a network is a data communication system that interconnects computer systems at different sites, or the connection of two or more computers using a communications system

Most networks can be classified into one of five different types. These include wide area networks (WAN), local area networks, (LAN), virtual private networks (VPN), client/server networks, network computing, and peer-to-peer networks.
