802.11 - 802.11 refers to a family of specifications developed
by the IEEE for wireless LAN technology. 802.11 specifies an
over-the-air interface between a wireless client and a base sta-
tion or between two wireless clients. The IEEE accepted the
specification in 1997.
802.11b - An extension to 802.11 that applies to wireless LANS
and provides 11 Mbps transmission (with a fallback to 5.5, 2
and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS.
DHCP (Dynamic Host Configuration Protocol) - A protocol for
assigning dynamic IP addresses to devices on a network. With
dynamic addressing, a device can have a different IP address
every time it connects to the network. In some systems, the
device's IP address can even change while it is still connected.
DHCP also supports a mix of static and dynamic IP addresses.
DNS (Domain Name System) - Is the system that is used to
translate Internet domain names into Internet Protocol (IP)
addresses. A domain name is a meaningful and easy-to-
remember "handle" for an Internet address.
DSSS (Direct-Sequence Spread Spectrum) - Is a transmission
technology used in wireless transmissions where a data signal
at the sending station is combined with a higher data rate bit
sequence, or chipping code, that divides the user data accord-
ing to a spreading ratio. The chipping code is a redundant bit
pattern for each bit that is transmitted, which increases the sig-
nal's resistance to interference. If one or more bits in the pat-
tern are damaged during transmission, the original data can be
recovered due to the redundancy of the transmission.
Dynamic IP Address - An IP address that is automatically
assigned to a client station in a TCP/IP network, typically by a
DHCP server. Network devices that serve multiple users, such
as servers and printers, are usually assigned static IP addresses.
