Using Wi-Fi (not available on all models)
User’s Guide 8–8
Encryption An alphanumeric (letters and/or numbers)
conversion process of data primarily used for
protection against any unauthorized
person(s).
Hotspots Public or private areas where you can
access Wi-Fi service. These wireless
connections can be located, for example, at
a library, cyber cafe, hotel, airport lounge,
or convention center. This service can be free
or sometimes requires a fee.
Infrastructure This connection mode uses wireless access
points to connect to networks.
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
(MAC) Address A computer’s unique hardware number in a
network, which also can provide security for
wireless networks. When a network uses a
MAC table, only the 802.11 radios (wireless
devices) that have had their MAC addresses
added to that network’s MAC table can
access the network.
