4.2.18 Networking glossary
numbers
10/100 Base-T: A technical term for Ethernet. 10/100 refers to the speed at which
the Ethernet network functions. 10 indicates 10 megabits per second (Mb/s) for
normal Ethernet, and 100 indicates 100 Mb/s for Fast Ethernet.
802.11a: A type of wireless networking that provides up to 54 Mb/s transmission in
the 5 GHz band.
802.11b: A type of wireless networking that provides up to 11 Mb/s transmission
(with a fallback to 5.5, 2 and 1 Mb/s) in the 2.4 GHz band.
802.11g: A type of wireless networking that provides up to 54 Mb/s transmission in
the 2.4 GHz band.

Ad hoc network: A type of wireless network in which devices directly communicate
with each other rather than through a Wireless Access Point (WAP). Ad hoc
networks are typically small and simple (for example, two wireless PCs or a wireless
PC and a wireless printer). Performance on these types of networks can degrade if
more than six devices are on the network. Ad hoc networks are also known as peer-
to-peer networks, independent basic service stations (IBSS), or direct-connect
wireless networks.
AES: Advanced Encryption Standard (AES) is a U.S. government sponsored
encryption method that uses a complex algorithm called “Rijndael.” AES uses
encryption keys to encode data. AES automatically changes the encryption keys
after a certain time interval, thus making the wireless network less vulnerable to
eavesdropping.
Authentication: Authentication is a wireless network security strategy. On a network
with authentication, devices use a shared key as a password and communicate only
with devices that know the key. Authentication does not encrypt the data sent
between wireless devices. Authentication can be used in conjunction with WEP.
Authentication keys and WEP keys can be identical.
