A-2
DB-26
“D” shaped 26-pin connector of either male or female gender.
DB-9
“D” shaped 9-pin connector of either male or female gender.
Degauss
Process of removing a magnetic charge from a material. Color screens are most susceptible to
this type of charge creating “purity” problems.
Dot pitch
Method of comparison used to determine the quality of a display. It indicates the angle and
proximity each dot has to the other.
DRAM
Dynamic Random Access Memory used for computer memory systems.
DTR
Data Terminal Ready signal used in communications protocol.
EEPROM
Electrically Erasable Programmable Read Only Memory. The portion of the monitor’s memory
which holds sysgen information and hardware configurations.
EMI
Electrical Magnetic Interference generated by repetitive signals such as microprocessor clocks
that can interfere with other devices or two-way radio communications.
EPP
Enhanced parallel port
ESD
Electrical Static Discharge. High voltage potentials carried on the body that are generated by
walking across a carpeted floor or caused by low humidity environments, which can be discharged
into an electronic device, damaging it.
Ethernet
The LAN technology that uses CSMA/CD physical access method and 10 Mbps digital
transmission. The forerunner of the IEEE802.3 CSMA/CD standard.
Ferrite
RF (radio frequency) glossy material used in EMI suppression.
FPGA
Field-programmable gate array.
Flexport
®
System Interface
Spacelabs Medical device that communicates via RS-232 with other manufacturer’s equipment.
GDS
Global Data System
