Although the company should not be confused about what are the differences between the local network (LAN) and wide area network (WAN) ”’ Too often, they find a bandwidth for their business are not clear on these basic principles of the entire network infrastructure’ If you are not completely understood, it affected the quality and accuracy of the final decision’ So ”’ it is important to do things’
So ”” For clarity of the real differences between the LAN and WAN:
LAN – A local area network (LAN) is a computer network covering a local area as a home, office or group of buildings close to each other’ Current LANs are most likely to be based on the IEEE 802′3 Ethernet switch, or the Wi-Fi operates at 10, 100 or 1000 Mbit’
In general, a local area network consists of local proximity to each other and finished the distance limitations’ The network can be wired or wireless, but there is only one place’
WAN – wide area network or WAN is a network that covers a large geographic area’ Contrast with personal networks (PAN), metropolitan area networks (MAN) or local area network (LAN), which are usually limited to a room, building or campus’ The biggest and best known example of a WAN is the Internet’
A wide area network (WAN) consists of multiple LANs interconnected across distances’ And, for example, an office attached to each of its satellite offices’ This method of interconnection is provided via third airline – that is, Qwest offers wiring dependent two places at once’
WAN is used to connect local area networks (LAN) and, so users and computers in one location can communicate with users and computers in other places’ WAN Many are built by an organization and are private’ Others, built by Internet service providers, provide connections from local network of organizations to the Internet’ WAN are often built using leased lines’ At each end of a leased line, a router is connected to the LAN on one side and a center within the WAN on the other’ Leased lines can be very expensive’ Instead of using leased lines, WANs can also be built using less costly circuit or packet switching methods’ Includes network protocols TCP provide transport functions and process’ Packet protocols, including SONET, MPLS, ATM and Frame Relay is often used by service providers to provide the links used in WANs’ X’25 WAN protocol is an early, and is often considered the “father” of Frame Relay as many protocols and functions of X’25 are still in use today (with upgrades) by Frame Relay’
