What Is The Real contrast between Lan And Wan Computer Network Infrastructures?

Although a business shouldn't be confused on what the differences are in the middle of Local Area Network (Lan) and Wide Area Network (Wan) ... Too often those entrusted with seeing a bandwidth solution for their business aren't clear on these basic tenets of full, computer network infrastructure. If not thoroughly understood it affects the ability and accuracy of the final decision. So ... It's prominent to get it right.

So .... In the interest of clarity here's the real differences in the middle of Lan and Wan:

High Bandwidth

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 based on switched Ieee 802.3 Ethernet, or on Wi-Fi technology running at 10, 100 or 1,000 Mbit.

In normal a local area network is made up of devices in local proximity to each other and has finite distance limitations. The Lan can be either wired or wireless but is only at a particular location.

Wan - A wide area network or Wan is a computer network covering a broad geographical area. Variation with personal area networks (Pans), metropolitan area networks (Mans) or local area networks (Lans) that are commonly microscopic to a room, construction or campus. The largest and most well-known example of a Wan is the Internet.

A wide area network (Wan) is comprised of many Lans linked to each other across distances. And example would be a corporate office linked to each of its satellite offices. This method of interconnection is handled via a third-party carrier -- i.e. Qwest provides the wiring connecting two locations together.

Wans are used to join together local area networks (Lans) together, so that users and computers in one location can recapitulate with users and computers in other locations. Many Wans are built for one particular club and are private. Others, built by Internet service providers, furnish connections from an organization's Lan to the Internet. Wans are most often built using leased lines. At each end of the leased line, a router connects to the Lan on one side and a hub 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 switching or packet switching methods. Network protocols including Tcp deliver vehicle and addressing functions. Protocols including Packet over Sonet, Mpls, Atm and Frame relay are often used by service providers to deliver the links that are used in Wans. X.25 was an prominent early Wan protocol, and is often carefully to be the "grandfather" of Frame Relay as many of the basic protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.
