Domain Name System
(DNS) A distributed name resolution system that enables computers to locate other
computers on a network or the Internet by domain name. The system
associates standard Internet Protocol (IP) addresses, such as “00.120.000.168,”
with host names, such as “www.sun.com.” Machines typically get this
information from a DNS server.
dual inline memory
module (DIMM) A circuit board that holds double the amount of surface-mount memory chips
that a single inline memory module (SIMM) holds. A DIMM has signal and
power pins on both sides of the board, whereas a SIMM has pins on only one
side of the board. A DIMM has a 168-pin connector and supports 64-bit data
transfer.
Dynamic Host
Configuration Protocol
(DHCP) A protocol that enables a DHCP server to assign Internet Protocol (IP)
addresses dynamically to systems on a Transmission Control Protocol/Internet
Protocol (TCP/IP) network.
dynamic random access
memory (DRAM) A type of random access memory (RAM) that stores information in integrated
circuits that contain capacitors. Because capacitors lose their charge over time,
DRAM must be periodically recharged.
E
electrically erasable
programmable read-
only memory
(EEPROM) A type of nonvolatile programmable read-only memory (PROM) that can be
erased by being exposed to an electrical charge.
electrostatic discharge
(ESD) The sudden dissipation of static electrical charge. ESD can easily destroy
semiconductor components.
Embedded Lights Out
Manager (ELOM) A dedicated system of hardware and supporting software that enables you
to manage your Sun server using several interfaces, independent of the
operating system, and under various power conditions.
enhanced parallel port
(EPP) A hardware and software standard that enables systems to transmit data at
twice the speed of standard parallel ports.
