LANs, MANs and WANs

Overview
Welcome to the level LANs, MANs & WANs level. Prepare to defeat these evil triplets with all your skills and knowledge. These three provide a challenge for all who dare to proceed.

LAN (Local Area Network):


A computer network that uses cables or radio signals to link two or more computers within a geographically limited area, generally one building or a group of buildings.
 * A networked office building, school or home usually contains a single LAN. The linked computers are called workstations.
 * EX. Business library, TC 201 classroom

MAN (Metropolitan Area Network):
A computer network that provides connectivity in a geographic area or region larger than covered by a LAN, but smaller than the area covered by a WAN. The term is applied to the interconnection of networks in a city into a single larger network, which may then also offer efficient connection to a WAN.


 * College or businesses man have a MAN that joins the different LANs across its campus.


 * EX. Area of Lansing

WAN (Wide Area Network):
A computer network that provides data communication services for business in geographically dispersed areas. A set of switches and routers are interconnected to form a WAN. The switches can be connected in different topologies, such as full mesh and half mesh. A WAN may be privately owned or rented from a service, but the term usually connotes the inclusion of public (shared user) networks.
 * Often connect multiple smaller networks, such as LANs and WANs
 * EX. The Internet is a WAN that spans the world
