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.
a
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.
