What is the Full Form of WAN

Full Form of WAN

The full form of WAN is “Wide Area Network”. A wide area network is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits.
WAN is a wide area network that covers a large geographic area consisting of two or more LANs or MANs. Or simply, we can say that a WAN is a group of local-area networks (LANs) or other networks that communicate with one another. This network is widely used to aid communication, the sharing of information, and large between devices. Know more here.

WAN History

The full form of WAN is described above. The first WAN was designed by the U.S. Air Force in the late 1950s. The roots of WAN are connected to the U.S Department of defence which developed ARPANET to let researchers communicate and share computer resources remotely from one device to another. The connection can be circuit-switched telephone lines, radio wave transmission, or optical fiber transmission. It is used to exchange data with users all over the world, they can be clients, employees, buyers, sellers, students, etc. Know about different aspects related to full form of WAN.

Advantages of WAN

We have seen the full form of WAN and also the related history of WAN. Here we have listed some of the advantages of WAN.
  • It divides the workload and drops travel charges.
  • WAN enables a user or workstation to unite with the world and allows them to transfer data and do business at a global level.
  • WAN facilitates a centralized data process. That means all workstations can share the data through the main server.
  • In WAN, the process of data transfer is quick and affordable because it covers a large geographical area.

Disadvantages of WAN

The full form of WAN is discussed here. We also have covered some of the advantages of WAN. Now we are going to see a few disadvantages of WAN.
  • Wide Area Networks can face traffic blockage.
  • WAN has very low fault tolerance ability.
  • The setup cost in WAN is high.
  • When it comes to security aspects, WAN is less secure as compared to LAN and MAN.
  • In WAN, you might feel the server issue.
  • The data transfer rate is slower than LAN.

Characteristics of WAN

In this article, we have also discussed a brief history of WAN. Here we are going to discuss some of the characteristics of WAN.
  • Higher Capacity: The capacity of WAN in terms of the number of LANs or WANs connected in a network is very high, which results in the connection of a large number of users over different locations all around the globe.
  • Broader Reach: The reach of WAN in terms of coverage of the geographical area is very high which can be a region, country, or the world itself.
  • Use of Public Carrier: WAN uses telephone networks, cabled systems, satellites, etc. for connection and transmission purposes which are easily available.
  • Resource Sharing: WAN enables its users to share data and information over a large area. Computer resources can be accessed remotely which makes transmission and exchange of data very easy.

Disadvantages of WAN

The full form of WAN is discussed here. We have also discussed some history of WAN. We also have discussed some disadvantages of WAN.
  • Traffic congestion in Wide Area Network is very high.
  • The data transfer rate is slow in comparison to LAN because of large distances and the high number of the connected system within the network.
  • The fault tolerance ability of WAN is very less.
  • Noise and error are present in a large amount due to multiple connection points.
