802.11a is an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps and an operating frequency of 5GHz.
802.11b is an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.
802.11g is an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps, an operating frequency of 2.4GHz, and backward compatibility with 802.11b devices.
802.11n is an IEEE wireless networking standard due out sometime in 2007 that specifies a maximum data transfer rate of 540Mbps, an operating frequency of 2.4GHz or 5GHz, and backward compatibility with 802.11b devices.
AP (Access Point) is a device that allows wireless-equipped computers and other devices to communicate with a wired network. Generally, the wireless adapter in the wireless network must connector to the Access Point then access the wireless network
A unit of data that is usually eight bits long.
Kbps (Kilobits per Second) is a unit of measurement for data transmission.
Mbps (Megabits per Second) is a unit of measurement for data transmission.
WEP (Wired Equivalency Protocol) is a security protocol for wireless networks. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. A shared key (similar to a password) is used to allow communication between the wireless adapter and the wireless AP/router.
WPA (Wi-Fi Protected Access) is a security protocol for wireless networks that builds on the basic foundations of WEP. It secures wireless data transmission by using a key similar to WEP, but the added strength of WPA is that the key changes dynamically. The changing key makes it much more difficult for a hacker to learn the key and gain access to the wireless network.
WPA2 (Wi-Fi Protected Access 2) is the second generation of WPA security and provides a stronger encryption mechanism through Advanced Encryption Standard (AES), which is a requirement for users who needs highest wireless security.
