Glossary

GL-4 Computer Group Literature Center Web Site

DRAM Dynamic Random Access Memory. A memory technology that is

characterized by extreme high density, low power, and low cost. It

must be more or less continuously refreshed to avoid loss of data.

DTE Data Terminal Equipment.

ECC Error Correction Code

ECP Extended Capability Port

EEPROM Electrically Erasable Programmable Read-Only Memory. A

memory storage device that can be written repeatedly with no

special erasure fixture. EEPROMs do not lose their contents when

they are powered down.

EISA (bus) Extended Industry Standard Architecture (bus) (IBM). An

architectural system using a 32-bit bus that allows data to be

transferred between peripherals in 32-bit chunks instead of 16-bit or

8-bit that most systems use. With the transfer of larger bits of

information, the machine is able to perform much faster than the

standard ISA bus system.

EPP Enhanced Parallel Port

EPROM Erasable Programmable Read-Only Memory. A memory storage

device that can be written once (per erasure cycle) and read many

times.

ESCC Enhanced Serial Communication Controller

ESD Electro-Static Discharge/Damage

Ethernet A local area network standard that uses radio frequency signals

carried by coaxial cables.

fast Ethernet See 100Base-TX.

FDC Floppy Disk Controller

FDDI Fiber Distributed Data Interface. A network based on the use of

optical-fiber cable to transmit data in non-return-to-zero, invert-on-

1s (NRZI) format at speeds up to 100 Mbps.

FIFO First-In, First-Out. A memory that can temporarily hold data so that

the sending device can send data faster than the receiving device can

accept it. The sending and receiving devices typically operate

asynchronously.
