GN-A11G Wireless LAN Access Point
Appendix A: Glossary Access Point
An Access Point is a wired controller that sends data to the wireless NIC’s
installed in your network computers, and received data back from them. An
Access Point is often connected to the network computer that has Internet
access, or is directly connected to an ADSL or cable modem.
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that
converts existing twisted-pair telephone lines into access paths for high-speed
communication of various sorts.
Auto-MDI/MDIX
On a network hub or switch, an auto-MDI/MDIX port automatically senses if it
needs to act as a MDI or MDIX port. The auto- MDI/MDIX capability eliminates
the need for crossover cables.
Auto-negotiate
To automatically determine the correct setting. The term is often used with
communications and networking.
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for
automating the configuration of computers that use TCP/IP. DHCP can be used
to automatically assign IP addresses, to deliver TCP/IP stack configuration
parameters such as the subnet mask and default router, and to provide other
configuration information such as the addresses for printer, time and news
servers.
DSSS
Also known as “Direct Sequence Spread Spectrum,” this is a variety of radio
transmission methods that continuously change frequenciesy or signal patterns.
Direct Sequence Spread Spectrum (DSSS), which is used in CDMA technology,.
multiplied the data bits by a very fast, pseudo-random bet pattern (PN sequence) that “spreads”
the data into a large coded stream that takes the full bandwidth of the channel.
