Device Server A specialized, network-based hardware device designed to perform a
single or specialized set of server functions. Print servers, terminal
servers, remote access servers and network time servers are examples
of device servers.
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.
DHCP consists of two components: a protocol for delivering host-
specific configuration parameters from a DHCP server to a host and a
mechanism for allocation of network addresses to hosts. (IETF
RFC1531.)
Option 78 specifies the location of one or more SLP Directory Agents.
Option 79 specifies the list of scopes that a SLP Agent is configured to
use.(RFC2610 - DHCP Options for Service Location Protocol)

DSSS Direct-Sequence Spread Spectrum. A transmission technology used in
Local Area Wireless Network (LAWN) 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 according 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. (Compare FHSS)
