    • What Is The Real Difference Between LAN And WAN Computer ...Although a business shouldnt be confused on what the differences are between Local AreaNetwork (LAN) and Wide Area Network (WAN) ... too often those entrusted with finding abandwidth solution for their business arent clear on these basic tenets of overall computernetwork infrastructure. If not completely understood it affects the quality and accuracy of thefinal decision. So ... its important to get it right. So .... in the interest of clarity heres the real differences between LAN and WAN:LAN - A local area network (LAN) is a computer network covering a local area, like a home, office,or group of buildings in close proximity to each other. Current LANs are most likely to be basedon switched IEEE 802.3 Ethernet, or on Wi-Fi technology running at 10, 100 or 1,000 Mbit.CLICK HERE TO GET INSTANT ACCESS TO CIRCUIT PROTOCOLSDownload this document if link is not clickableIn general a local area network is made up of devices in local proximity to each other and hasfinite distance limitations. The LAN can be either wired or wireless but is only at a single location.WAN - A wide area network or WAN is a computer network covering a broad geographical area.Contrast with personal area networks (PANs), metropolitan area networks (MANs) or local areanetworks (LANs) that are usually limited to a room, building or campus. The largest and mostwell-known example of a WAN is the Internet.A wide area network (WAN) is comprised of multiple LANs connected to each other acrossdistances. And example would be a corporate office connected to each of its satellite offices. Thismethod of interconnection is handled via a third-party carrier -- i.e. Qwest provides the wiringconnecting two locations together.WANs are used to connect local area networks (LANs) together, so that users and computers in
    • one location can communicate with users and computers in other locations. Many WANs are builtfor one particular organization and are private. Others, built by Internet service providers, provideconnections from an organizations LAN to the Internet. WANs are most often built using leasedlines. At each end of the leased line, a router connects to the LAN on one side and a hub withinthe WAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANscan also be built using less costly circuit switching or packet switching methods. Networkprotocols including TCP deliver transport and addressing functions. Protocols including Packetover SONET, MPLS, ATM and Frame relay are often used by service providers to deliver the linksthat are used in WANs. X.25 was an important early WAN protocol, and is often considered to bethe "grandfather" of Frame Relay as many of the underlying protocols and functions of X.25 arestill in use today (with upgrades) by Frame Relay.For professional help in finding just the right LAN or WAN solution for your business applications.... use the no cost assistance available through DS3-Bandwidth.com.CLICK HERE TO GET INSTANT ACCESS TO CIRCUIT PROTOCOLSDownload this document if link is not clickableArticle source = ezinearticles.com/?What-Is-The-Real-Difference-Between-LAN-And-WAN-Computer-Network-Infrastructures?
