WAN — Wide Area Network
The abbreviation, acronym or full form of WAN is Wide Area Network
Abbreviation, Acronym & Full Form of WAN
A wide area network is a network that covers a broad area using private or public network transports. It is a global network which spans across several countries and territories. A WAN is usually made up of several computer networks connected together. A WAN can be viewed as a computer networking technology that can be used to transmit data over long distances and between different LANs, and other localized computer networking architectures. Many business sectors and companies utilize WAN to relay data among employees, clients, buyers, and suppliers from various geographical regions. Internet is the best example of a wide area network.
WANs are used to connect LANs and other types of networks together so that users and computers in one location can communicate with users and computers in other locations thereby acting as a media for the transfer of information and contributing towards communication across various parts of the world.
WAN Full-Form refers to Wide Area Network. WAN is a computer or telecommunications network that is spread over a wide geographical area. Leased lines or leased telecommunication circuits are usually used for establishing WANs. Numerous government, educational and business organizations use WANs for relaying data among buyers, students, suppliers, clients and staff from a number of geographical establishments. This telecommunication mode helps a business in carrying out its daily functions effectively irrespective of its location. A common example of a WAN is the Internet.
A WAN can span over regions, nations or even the entire world. WANs can be viewed as the technologies pertaining to computer networks that are used for transmitting data and information over large distances, and also between various localized networking architectures like MANs or metropolitan area networks and LANs or local area networks. WANs also perform other functions in addition to connecting physically different LANs. For example, a CAN or campus area network may use WAN technologies for connecting various local area networks within the same campus.
This can be done for facilitating the applications of higher bandwidth, or for giving better functionalities to the users of the campus area network. LANs and other network types can be connected with each other by using WANs. This application can enable communication between computers and users in one location with those from other locations. Each organization has its own WAN and is private to that organization. There are certain other WANS that are made by ISPs or Internet Service Providers for providing connections from the LAN of an organization to the internet.
As discussed above, leased lines are often used for building WANs. However, they can prove to be costly. Therefore, less costly methods like packet switching methods or circuit switching methods can be used for building WANs. The addressing and transport functions are carried out by the network protocols like TCP/IP. WAN optimization of WAFS (wide-area file services) can be used for delivering performance improvements.
Benefits of WAN –
- Connects different people across the world by establishing a global network.
- Favours communication and transfer of information.
- Many organizations and businesses across the world are running successfully due to this global network.
- Essential for the proper functioning of various transportation sectors across the world including airlines, railways and waterways.
