F
fault symptom code (FSC)
A hexadecimal code generated by the drive or the control unit microcode
in response to a detected subsystem error.
FC Feature code.
FCC Federal communications commission.
FE Field engineer, customer engineer, or service representative.
fiducial
A target used for teaching a physical location to a robot.
field replaceable unit (FRU)
An assembly that is replaced in its entirety when any one of its
components fails.
file A named set of records stored or processed as a unit. Also referred to as a
dataset.
file protection
The processes and procedures established in an information system that
are designed to inhibit unauthorized access to, contamination of, or
deletion of a file.
file transfer protocol (FTP)
In the Internet suite of protocols, an application layer protocol that uses
TCP and Telnet services to transfer bulk-data files between machines or
hosts.
firmware
Proprietary code that is usually delivered as microcode as part of an
operating system. Firmware is more efficient than software loaded from an
alterable medium and more adaptable to change than pure hardware
circuitry. An example of firmware is the Basic Input/Output System (BIOS)
in read-only memory (ROM) on a PC motherboard.
FLASH EEPROM
An electrically erasable programmable read-only memory (EEPROM) that
can be updated.
FMR
Field microcode replacement.
format
The arrangement or layout of data on a data medium.
formatter
Part of a magnetic tape subsystem that performs data conversion, speed
matching, encoding, first level error recovery, and interfaces to one or more
tape drives.
FP File protect.
frayed Damaged as if by an abrasive substance.
FRU Field replaceable unit.
FSC Fault symptom code.
FSI Fault symptom index.
functional microcode
Microcode that is resident in the machine during normal customer
operation.
