A LAN (local area network) is a group of computers and network devices connected together, usually within the same building
A WAN (wide area network), is not restricted to a geographical location, although it might be confined within the bounds of a state or country. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive. The internet is an example of a worldwide public WAN.
Lastly, the protocols are different between a LAN and WAN. A LAN uses transmissions to other devices within the same network segment, whereas a WAN uses point to point transmissions between nodes of the WAN which may be separated by hundreds or thousands of miles.
lan is used for a home or small buisness network. That's how it got its name: Local Area Network
Where a WAN is used for a bigger buisness or college. That's how that got its name: Wide Area Network.
A LAN is a local network that consists of computers and network devices that are connected together, perhaps in a work related situation. The WAN is a wide area network. A AN connects several LANS and can either be used by large corporations or the public.
1. A LAN is a data communication system within a building,plant,or campus ,or between nearby buildings. A WAN is a data communication system spanning ststes, countries, or the whole world. 2. Currently ,LAN size is limited to a few kilometers. WAN provides long-distance transmission of data,image,audio, and video information over large geographic areas. 3. LAN will use only one type of transmission medium. the most common LAN topologies are: bus,ring,star. Wireless LANs are the newest evolution in LAN technology. 4. ex of LAN: LAN in business envirnments links a workgroup of task-related computers -like-engineering workstations or accounting PCs. ex of WAN: asynchrnous transfer mde(ATM) network-which is a network with fixed size data unit packets called cells. wireless WAN
What seperates a LAN, MAN, WAN etc is actually the geographical area they cover. For example, a single computer with a mouse and a keyboard is a network, specifically a Personal Area Network or PAN. Now, technically speaking, the WAN is usually owned by an ISP which is responsible for providing high speeds and a stable connection. A "wider" network sometimes connect two smaller networks, for example a WAN can virtually connect two LANs (virtually means they are not directly connected with a single cable but they use the WAN to accomplish that).
Lan usually has higher data-transfer rates and smaller geographic area. While Wan is a computer network that includes everything.
distance covered by lan
From the user's point of view, accessing a LAN or WAN is the same. If packets need to be forwarded from a LAN via a WAN connection that is taken care of automatically by the router.
LAN is internal. IE, your computer, router, modem. WAN is external, such as your computer, a server on the internet, a corporate database. Not to be confused with WLAN, which is wireless LAN
if the LAN is connected to another LAN over a wide distance using point to point links then it becomes part of the WAN (but it doesn't become a WAN by itself).
see: Difference_between_LAN_and_WAN
It all depends on perspective. If you look at it as a IP network, the difference is routers used in WAN. If you take in account DNS and other Internet services, the difference is more dramatic.
No
WAN usually costs more. Especially, there are recurring monthly costs, since you rent the services of an ISP. Note, however, that a LAN and a WAN serve different purposes; you can't simply replace a WAN with a LAN.
GWAN = Gigabit WAN WAN = Wide Area Network LAN = Local Area Network WLAN = Wireless Local Area Network MAN = Metropolitan Area Network
WAN. LAN is a short range connection, WAN is wide range.
A LAN has a limited length for distance, and for the number of clients that may be connected to it. If you exceed either, then you may need a longer connection distance, which is afforded by a WAN.
absolutely wan. lan is used for a office or a building complex
LAN is the Local Area Network while the WAN is the Wide Area Network.
