are not nearly as many as there are LAN’s.Another very popular network is the WAN (wide area network). A WAN is basically used in to go from building to building across a city. To have make a MAN, the network size has to fall in-between the size of LAN’s and WAN’s. A MAN typically covers an area of between 5 and 50 km diameter. In some cases MAN’s may be as small as a group of buildings or as large as the North of Scotland. Some of the other types of network are: Storage Area Network (SAN), System Area Network (SAN), Server Area Network (SAN), Small Area Network (SAN), Personal Area Network (PAN), Desk Area Network (DAN), Controller Area Network (CAN), and a Cluster Area Network (CAN). All of these networks are very good networks and they help all business today. There will probably be even more different types of networks that are made up, as the technology world keeps advancing. I think sometime there will be another kind of WAN that will take the current WAN’s place. This new one will probably be a lot more efficient and reliable....
