Wide+Area+Network+(WAN)

A Wide area network is basically a international router connected to your home router which sends and receives information to and from your router, WAN is usually used for people trying to contact other people from different countries E.G. England & U.S.A if someone from England wanted to contact a relative or friend in America then they would first have to send some information to the right international router and then the international router will send the information on a journey and it will be received by your relative or friend in America. Furthermore Wide area network is a telecommunications network which can cover a broad area. This particular system is good because it can link important places such as metropolitan, regional or national boundaries. The main people that use WAN are buisnesses and government because they can easily relay important data to other clients, buyers and suppliers from all around the world. WAN Allows buisnesses to carry out there daily function regardless of the location they are sending the data to. WANs are used to connect LANs and other types of networks together they do this because this ensures that users and computers in one location can communicate with users and computers in a different location regardless how far away it is. Most WANs are normally made for one particular organization and are usually private so the people within the buisness or other people that are enabled to access can access the network. Other Internet Service providers provide connections from an organization's LAN to the internet. WANs are built out of leased lines, At each end of the leased lines there is usually a router connects to the LAN on one side with a second router within the LAN on the other end of the leased line.

Wide area network is alot better than LAN because if your using WAN then you can communicate with people over the other side of the world if you want to send a relative or friend data accross sea for example then you will need to use WAN, First you have to send the data you wish to send to the international or regional router you need and then the router you have sent it to then forwards it onto the person or people that it was intended to get to, WAN has its disadvantages to LAN one main disadvantage is that it has really slow data transfer rate because if your sending a data packet accross sea From England to U.S.A then it will take a lot longer than if you were sending a data packet in your own home or a buisness office which uses LAN. Although it has disadvantages its main advantage is that you can send data to other countries and or continents with ease and efficency. Also you can receive the information back from the other person you sent the information but they will have to do the visa versa of what you done to send yours to them.
