What’s the difference between LAN and WAN and other networks?
web connection types differ fromnetwork topologies(such as bus, ring, and star).
LAN: Local Area data pipe
ALANconnects data pipe devices over a relatively short distance.

InTCP/IP networking, a LAN is often, but not always, implemented as a single IPsubnet.
These networks also tend to use certain connectivity technologies, primarilyEthernetandToken Ring.
WAN: Wide Area connection
AWANspans a large physical distance.
The internet is the largest WAN, spanning the Earth.
A WAN is a geographically-dispersed collection of LANs.
A online grid gadget called a router connects LANs to a WAN.
In IP networking, the router maintains both a LAN address and a WAN address.
A WAN differs from a LAN in several important ways.
Most WANs (like the internet) aren’t owned by a single organization.
Instead, WANs exist under collective or distributed ownership and management.
WANs tend to use technology likeATM,Frame Relay, andX.25for connectivity over the longer distances.
