Glossary 697
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 that is 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.
