usually a corporation, accessible only by the organization's members, employees, or

An identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP
protocol route messages based on the IP address of the destination. The format of an
IP address is a 32-bit numeric address written as four numbers separated by periods.
Each number can be zero to 255. For example, 22.214.171.124 could be an IP address.
Abbreviation of integrated services digital network, an international communications

Local Area Network (LAN)
A computer network that spans a relatively small area. Most LANs are confined to a
single building or group of buildings. However, one LAN can be connected to other
LANs over any distance via telephone lines and radio waves. A system of LANs
connected in this way is called a wide-area network (WAN)
Short for Media Access Control address, a hardware address that uniquely identifies
each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of
the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC)
layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly
with the network media. Consequently, each different type of network media requires a
different MAC layer.
