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
signal's resistance to interference. If one or more bits in the
pattern are damaged during transmission, the original data can
be recovered due to the redundancy of the transmission.
DTIM Interval- This value indicates the interval of the Delivery
Traffic Indication Message (DTIM). A DTIM field is a countdown
field informing clients of the next window for listening to broadcast
and multicast messages. When the Access Point has buffered
broadcast or multicast messages for associated clients, it sends
the next DTIM with a DTIM Interval value. Access Point Clients
hear the beacons and awaken to receive the broadcast and
multicast messages.
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.
FHSS (Frequency-Hopping Spread Spectrum) - Is transmission
technology used in wireless transmissions where the data signal
