Telecommunications network is a combination of nodes and links which are arranged in a manner so that the message may pass from the one part of the network to the other by traveling over variable nodes.
Essential Parts of the Network
There are five basic segments of this type of network. These parts include terminals, channels, processors, computers and control softwares. The starting and ending point of the telecommunication networks is known as a network terminal. There are many input and output devices which are often placed under the heading of terminals. Telecommunication processors are often helpful in transferring data between the terminals of the network. These processors also provide variety of control and support functions. Telecommunication channels are the reception and transmission point for the data and messages. The network computers are arranged in a manner so that they establish a network connection using different media, these computer terminals help in communication. Telecommunication network software governs the control and functional activities with the help of software in a network. The structure of telecommunication network has three main components the control plane, the user plane and the management plane. As indicated by its name the control plane carries control information and data. The data plane or user plane monitors the user traffic in the network. The third and last component management plane carries the operation and administration traffic over the network.
Types of Telecommunication Networks
Telecommunication network has many types like wide area network, metropolitan area network, local area network, campus area network, personal area network, virtual private networks, client server network, peer to peer network, network computing. The network which is spread over a large geographic area is known as wide area network. This network has helped businesses which are dispersed over different regions to communicate to the head office. Metropolitan area network covers the area of nearly one city or county. Its area and coverage is more than the local area network and less than the wide area network. The communication of computers in a very small geographical area is known as local area network. Campus area network is a network which is restricted to the small geographical area which is limited to the university campus or a building. Personal area network is a network which is limited to an individual. Virtual private network is built on the principle of secure encrypted network in order to provide complete security to the users. The client server network is network which is connected to the LAN at one end and the back up server at the other end. When a computer uses network browser to connect to the other computers in the network it is known as network computing. Microsoft office online is the good example of such kind of network. Peer to peer network is used for connecting only those computers which have copy rights to use each others resources.
Examples of a Telecommunication Network
The first example of the telecommunication network is computer networks .computer network is set of computers which are attached to each other for the purpose of resource sharing. The second example is the internet. Internet is the global network which allows the users in many dispersed areas to connect via web browsers and telecommunication technologies provide by internet services providers. Third example is of the public switched telephone networks, it is a circuit switched network which used to carry analog signals but now it carries digital signals mostly. The fourth example is the working of global telex; it is a set of machines which include teleprinters and tele typewriters. The last example is of the aircraft communication addressing and reporting system.
