A local area network is a network that spans a relatively space and provides services to a small number of people
Local Area Network
Wide area network (WAN) that is usually a larger network that covers a large geographic area.
WAN Wide area network
WAN (Wide Area Network)
City networks are commonly known as WAN's, or Wide Area Network's.
A LAN (Local Area Network) unless it is over a large geographical area then it would be a WAN (Wide Area Network).
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network,It is also used to mean the interconnection of several local area networks by bridging them with backbone lines.
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.
Lan is a local network such as inside a house or building, or a wireless covering an area locally. Wan is a wide area network such as the Internet. This network covers a large area (can include the world). Wan's consist of many local area networks linked together.
LAN stands for "Local Area Network" while it can cover a large area they usually don't. For example an office building generally uses a LAN. And if in a skyscraper that LAN can be quite large. On the same token, if you have a router at your house, and all the computers on that router are connected via ethernet cables. That is also a LAN, but is much smaller.
A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN).
There is only one type of LAN. If you are asking for the type of networks then they are the following: LAN - Local Area Network WLAN - Wireless Local Area Network VLAN - Virtual LAN WAN - Wide Area Network MAN - Metropolitan Area Network SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network PAN - Personal Area Network DAN - Desk Area Network
