LAN A LAN is a computer network that connects a relatively small area (a single building or group

of buildings). Most LANs connect work stations and computers to each other. Each computer

(also known as a “node”) has its own processing unit and executes its own programs;

however, it can also access data and devices anywhere on the LAN. This means that many

users can access and share the same information and devices. A good example of a LAN

device is a network printer. Most companies cannot afford the budgetary or hardware expense

of providing printers for each of its users; therefore, one printer, (i.e., device) is placed on the

LAN where every user can access the same printer.

The LAN uses IP addresses to route data to different destinations on the network. An IP

address is a 32-bit numeric address written as four numbers separated by periods (for

example, 1.160.10.240).

Port A port, when referring to TCP and UDP networs, is an endpoint in a logical connection. The

port number identifies the type of port it is. For example, port 80 is used for HTTP traffic.

Routers A router is a device that forwards data packets over networks. Most commonly, a router is

connected to at least two (2) networks (normally LANs or WANs). Routers are located at

gateways, the place where two networks are connected. Routers do little data filtering, they

mainly deliver the data.

Subnet A subnet is a portion of a network that shares a common address component. On a TCP/IP

network, a subnet is described as all computers or devices whose IP Address have the same

prefix.

Subnetting a network is useful because it provides security for the network, as well as,

increases performance of the network. IP networksare divided using subnet masks.

Switches A switch is a device that filters and forwards data packets between networks. Switches

operate at the data layer, and sometimes at the network layer.

WAN A wide area network connects two or more LANs and can span a relatively large geographical

area. For example, Telex Headquarters in Burnsville, MN is connected to several branch

offices in Nebraska and Arkansas over the wide are anetwork. The largest WAN is the

Internet.
