Appendix A: Glossary
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.
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that converts exist-
ing twisted-pair telephone lines into access paths for high-speed communications of vari-
ous sorts.
Auto-negotiate
To automatically determine the correct settings. The term is often used with communica-
tions 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 as-
sign 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 ad-
dresses 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 frequencies or signal patterns. Direct Sequence Spread
Spectrum (DSSS), which is used in CDMA, multiplies the data bits by a very fast, pseudo-
random bit pattern (PN sequence) that “spreads” the data into a large coded stream that
takes the full bandwidth of the channel.
Access Point
An access point is a wired controller that sends data to the wireless NICs installed in your
network computers, and received data back from them. An AP is often connected to the
Network computer that has Internet access, or is directly connected to a ADSL or cable
modem.
