DEFINES paragraph. An optional paragraph in the CONFTEXT configuration file that
contains one or more identifiers, each with its associated text string. The DEFINES
paragraph, if used, precedes the ALLPROCESSORS paragraph.
delta. A method for connecting a 3-phase power source (or load) in a closed series loop
with input (or output) connections made to each of the three junctions. The delta’s
physical arrangement resembles the delta character from the Greek alphabet.
demon. On a UNIX system, a process that runs continuously to provide a specific service
for other processes. A demon does not have a controlling terminal and is not explicitly

(OSS) environment and has an OSS process ID. See also static server
.
dest PID. See destination PID (dest PID).
destination control table (DCT). The HP NonStop™ operating system data structure that
holds information about every device and named process in the system. The DCT
consists of the named resource list (NRL)
and the process-pair list (PPL). The DCT is
replicated in each CPU.
destination PID (dest PID). The destination processor for a packet generated by an
input/output application-specific integrated circuit (ASIC).
destination ServerNet ID (DID). A field in the ServerNet packet header indicating the
intended destination for the packet.

DHCP. See Dynamic Host Configuration Protocol (DHCP).
dial-out point. A system console from which incident reports are sent to a service provider.
Incident reports are sent only from system consoles defined as the primary and backup
dial-out points (the primary and backup system consoles).
DID. See destination ServerNet ID (DID).
DIMM. See dual inline memory module (DIMM).
direct connect. Connection from the Fibre Channel ServerNet adapter (FCSA) to the
Enterprise Storage System (ESS)
without going through an FC switch.
direct current (DC). Electric current that flows in only one direction. Contrast with
alternating current (AC)
.
