[pic] LAN SETUP

IEEE has produced several standards for LANs. These standards collectively known as IEEE 802 .
IEEE802.3 (Ethernet), IEEE802.4 (Token Bus), IEEE802.5 (Token Ring)

WAN (WIDE AREA NETWORK)

It is a Computer network that spans a relatively large geographical area, often a country or continent. Typically a WAN consists of two or more Local Area Network.
Computers connected to WAN are often connected through public networks such as telephone systems. They can also be connected through leased lines or satellites. The largest WAN in existence is Internet.
WANs run at speed of maximum 2 to 10 Mbps.

WAN SETUP

For most WANs, the long distance bandwidth is relatively slow: on the order of kilobits per second (kbps) as opposed to megabits per second (Mbps) for local-area networks (LANs). For example, an Ethernet LAN has a 10 Mbps bandwidth; a WAN using part or all of a T1 carrier has a bandwidth of 1.544 Mbps .

Three types of approaches are used to connect WANs:

1) Circuit switching, which provides a fixed connection (at least for the duration of a call or session), so that each packet takes the same path. Examples of this approach include ISDN, Switched 56, and Switched T1.

2) Packet switching, which establishes connections during the transmission process so that different packets from the same transmission may take different routes and may arrive out of sequence at the destination. Examples of this approach are X.25,
