DRAC
Refers to a remote management capability. See RAC.
DRAM
Acronym for dynamic random-access memory. A computer's RAM is usually made
up entirely of DRAM chips. Because DRAM chips cannot store an electrical charge
indefinitely, your computer continually refreshes each DRAM chip in the
computer.
drive-type number
Your computer can recognize a number of specific hard drives. Each is assigned
a drive-type number that is stored in NVRAM. The hard drive(s) specified in your
computer's System Setup program must match the actual drive(s) installed in the
computer. The System Setup program also allows you to specify physical
parameters (logical cylinders, logical heads, cylinder number, and logical sectors
per pack) for drives not included in the table of drive types stored in NVRAM.
DTE
Abbreviation for data terminal equipment. Any device, such as a computer system,
that can send data in digital form by means of a cable or communications line.
The DTE is connected to the cable or communications line through a data
communications equipment (DCE) device, such as a modem.
ECC
Abbreviation for error checking and correction.
ECP
Abbreviation for Extended Capabilities Port.
EDO
Acronym for extended data output dynamic random access memory which is a
type of DRAM faster than conventional DRAM. EDO RAM can start fetching
the next block of memory at the same time that it sends the previous block to the
CPU.
EEPROM
Acronym for electrically erasable programmable read-only memory.
EIDE
Abbreviation for enhanced integrated drive electronics. EIDE devices add one or
more of the following enhancements to the traditional IDE standard:
