The next topic I want to look at is the topic of WAN and MAN.
WAN (wide area network)
A WAN is a wide area network. Generally, a WAN is one large network that covers a large geographical area. One of the best known WANs would be the internet. While WANs cover large geographical areas, they don’t have to be one single network covering the large geographical area.
A WANs can be made up of a lot of different smaller networks in different parts of a geographic area that are all linked together to form a large wide area network.
In the event that you have a lot of smaller networks all linked together into a large wide area network, and that configuration is owned by a single company or single organization, then that kind of a network is often referred to as an enterprise network. Because of the size and scale of WANs, generally use routers and occasionally switches to connect up all the disparate networks that make up a large WANs. Another type of network is called a MANs.
MAN (metropolitan area network)
A MAN stands for metropolitan area network and it uses the same technology as a WAN. The difference is a MAN covers a much smaller area. In general, a MAN is only going to cover an area of only about 50 kilometers across, give or take a little. One thing to keep in mind about the term MAN is that it is falling out of use. Instead, more and more we’re using the term WAN to apply to both WANs and MANs.
