We all are familiar with the word WAN,but most of us are not aware about the benefits of WAN,here is a brief description of WAN and its benefits
WAN (Wide Area Network) is a common term in networking. To better understand it, you should know about LAN (Local Area Network).
LAN (Local Area Network) is network of a company where the computers can be connected up to limited area. Approximately this network can be configured well up to 100 meters distance. The computers are connected through devices like Switches. These kinds of networks are limited to a building or campus. The users can share the network resource and securities can be implemented only within the network.
WAN (Wide Area Network) connects two or more LANs and other networks so that computers at one location can communicate to the computers at far away some other location. Some Wide Area networks are built by private companies and only works for them and other are built by some Internet Service Providers. WANs are usually built through leased lines and routers are used to connect the network at one place to the network at other place. For example, a company has a network in UK. The company wants to open its office in USA. In order to connect the two offices in UK and USA, we have to install routers at both ends for communication.
We can have unprecedented benefits from WAN. By sitting at one city or country the user can share the resources of the network in other city or country. For example the user can print the document or send an instant message by just one click. The users can use online softwares for communication and can work at the same time on the server database. The benefits are unlimited and it's up to the organization to what extent they need it for them
