If you are using LAN such a school, College, Offices Quarters it can be thousand and above users.

What is a WAN(Wide Area Network)

A Wide Area Network is also known as WAN. WAN is a large network of connections of multiple resources or devices that can be accessed from single points of the location. WANs can allow facilitating communication, the sharing of information, resources, and much more between devices from around the world through a WAN provider.

Wide Area Network

Wide Area Network provides no limit to the distance you can get access to information from any location. In most WANs, You can access your network consists of two distinct components circuits or channels or links and switching and routing devices (switches & routers). Transmission-lines are used for moving data between machines, whereas routers are used to connect two or more transmission lines.

From the help of the Wide Area Network, users can access resources for long-distance transmission of data, voice, image, and video information over large geographical areas that may comprise a country, a continent, or even the whole world.

The main purpose for Wide Area Network As organizations grow and become international Plateform, WANs allow them to communicate between branches, share information, and stay connected.
