Technical data

FDDI
See Fiber Distributed Data Interface.
fetch/store operation
The operation of two commands that allow a system manager to fetch a value from
a data item or to store a value into a data item.
Fiber Distributed Data Interface (FDDI)
The high-speed (100 mb/s) networking standard based on fiber optics, established
by the American National Standards Institute (ANSI); uses 1300 nanometer light
wavelength. FDDI networks are limited to approximately 200 km in length, with
repeaters every 2 km or less.
file
A uniquely named collection of information with shared managerial and structural
properties.
file attribute
The characteristic of a file, such as its size or creation date. The values of some
file attributes may change during the lifetime of a file.
file data
The information that is stored within a file and comprises its contents (as opposed
to its attributes).
file designation
System-specific information that identifies a file on its storage system.
file server
The host whose principal purpose is to store files and provide network access to
them.
file specification
System-specific information that identifies a file on its storage system.
file system
A method for recording, cataloging, and accessing files on a volume.
File Transfer Protocol (FTP)
The protocol and software that permit a user on one host to access and transfer files
to and from another host over a network. See also Trivial File Transfer Protocol.
Files-11On-DiskLevel2orLevel5(ODS-2orODS-5)
The set of rules that govern the organization of the OpenVMS file system, external
to the files themselves.
FINGER utility
The utility that provides information about users on local and remote systems.
flow control
(1) The function of a receiving entity to limit the amount or rate of data that is sent
by a transmitting entity. (2) The control of the rate at which hosts or gateways
inject packets into a network or Internet, usually to avoid congestion. Flow control
mechanisms can be implemented at various levels and allow communicating layers
to match their data transfer and receive rates. Simplistic schemes, like ICMP
source quench, simply ask the sender to cease transmission until congestion ends.
More complex schemes vary the transmission rate continuously.
