GL-5

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.

Falcon The DRAM controller chip developed by Motorola for the

MVME2600 and MVME3600 series of boards. It is intended

to be used in sets of two to provide the necessary interface

between the Power PC60x bus and the 144-bit ECC DRAM

(system memory array) and/or ROM/Flash.

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.

ﬁrmware The program or specific software instructions that have

been more or less permanently burned into an electronic

component, such as a ROM (read-only memory) or an

EPROM (erasable programmable read-only memory).

frame One complete television picture frame consists of 525

horizontal lines with the NTSC system. One frame consists

of two Fields.

graphics controller On EGA and VGA, a section of circuitry that can provide

hardware assist for graphics drawing algorithms by

performing logical functions on data written to display

memory.

HAL Hardware Abstraction Layer. The lower level hardware

interface module of the Windows NT operating system. It

contains platform specific functionality.
