4. Glossary<br />
802.1x: The IEEE 802.1x is a standard for user authentication on networks.<br />
Access Point: A hardware device or a computer's software that seamlessly connects wired<br />
and wireless networks.<br />
Ad-Hoc: An independent wireless LAN network formed by a group of computers equipped<br />
with wireless network adapters.<br />
ADSL: Asymmetric Digital Subscriber Line is a new technology that allows more data to be<br />
sent over existing copper telephone lines. ADSL supports data rates from 1.5 to 8 Mbps<br />
downstream and from 16 to 640 Kbps upstream.<br />
ASCII: American Standard Code for Information Interchange is a code for representing<br />
characters as numbers. Each letter is represented as a number from 0 to 127. ASCII was<br />
originally developed for communications and uses only seven bits per character. Since<br />
computers use 8-bit byte (256 character combinations) and ASCII uses only the first 128 (0-<br />
127), the second set of 128 characters (128-255) are technically not ASCII, but are typically<br />
used for different language and math symbols representation.<br />
Authentication: The process of identifying a network client usually based on a username and<br />
password.<br />
Beacon: A beacon is a packet broadcasted by the Access Point / Router in order to keep the<br />
network synchronized.<br />
CCX: The Cisco Compatible eXtensions Program for WLAN devices, is a program that<br />
provides compatibility testing for compliance with proprietary Cisco wireless features.<br />
Channel: A channel is a separate path through which signals can flow.<br />
DHCP: Dynamic Host Configuration Protocol is a protocol that automatically assigns dynamic<br />
IP addresses to devices on a network.<br />
DSSS: Direct Sequence Spread Spectrum is a transmission technology where a data signal<br />
is combined with a higher data rate bit sequence. The additional bits increase the signal's<br />
resistance to interference.<br />
