virtual private network, is one such security measure to protect the intelligence of the LAN. A computer outside the LAN must

have an address or key known by the VPN to allow access to the LAN. Many companies use a VPN to connect two different

LANs, thus allowing the transfer of data between two networks.

LAN (local area network) vs. WAN (wide area network)

Local Area Network

Simply put, a LAN (Local Area Network) is a computer network that connects a relatively small area (a single building or

group of buildings). Most LANs connect workstations 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 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 (or 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

consisting of four numbers separated by periods (for example, 1.160.10.240).

NOTE: For more information on IP Addresses, see you local network administrator.
