Internet Protocol (IP)
Address
A 128-bit number that identifies each sender or
receiver of information that is sent in packets
across the Internet. For example, when you
request an HTML page or send e-mail, the Internet
Protocol part of TCP/IP includes your IP address
in the message. In this example, this information
identifies your computer as the sender and/or
receiver of information.
Media Access Control

A computer’s unique hardware number in a

that have had their MAC addresses added to that
network’s MAC table can access the network.
Security Set Identifier

alphanumeric, case-sensitive name given to each
ESS.
