Fundamentals of WAN

A collection of networks and/or local area networks (LAN) which communicate with each other is called a wide area network (WAN). A telecommunication network is extended over the geographical area for the basic computer network purpose (by connecting all smaller networks). From any part of the world, WAN allows communication and sharing the data between devices.
