Facsimile :
A system for the transmission (usually over a voice-grade
channel) of a picture, drawing or document, with reproduction
at the receiving end.
FAQ :
(Frequently Asked Questions) FAQs are documents that list and
answer the most common questions on a particular subject.
There are hundreds of FAQs on subjects as diverse as Pet
Grooming and Cryptography. FAQs are usually written by people
who have tired of answering the same question over and over.
FAT :
Slim-Fast is useless to eliminate it ! File Allocation Table.
In a DOS system, this table contains for each file its address
on the disk.
Fault Tolerance :
The ability to produce correct results, even in the presence
of faults or errors, by the use of redundancy hardware or
checking techniques.
Fax :
Abbreviation for facsimile.
FCC :
Federal Communications Commission. The U.S. federal agency
responsible for regulating interstate telecommunications, as
well as international telecommunications aspects of cellular
communications and broadcasting. The FCC was established by
the Communications Act of 1934.
FDDI :
Fiber Distributed Data Interface. An American National
Standards Institute standard for 100 Mbps fiber-optic local
area networks. Incorporates token processing and supports
circuit-switched voice and packetized data. Components
include: PMD (Physical Layer Medium Dependent), which deals
with physical connections including fiber links, cables and
connectors.; PHY (Physical Layer Protocol) which includes the
encoding/decoding of packets and data clocking; MAC (Media
Access Control) which includes parameters for token passing,
addressing, packed sizes and framing; and SMT (Station
Management) which governs management of the physical network.
Fiber Optics :
A high-bandwidth transmission technology that uses light to
carry digital information. One fiber telephone cable carries
hundreds of thousands of voice circuits. These cables, or
light guides, replace conventional coaxial cables and wire
pairs. Fiber transmission facilities occupy far less physical
volume for an equivalent transmission capacity, which is a
major advantage in crowded ducts. Optical fiber is also immune
to electrical interference.
File :
Set of apparent records considered as a unit for storage.
File Server :
A computer containing files available to all users connected
to a local-area network (LAN). In some LANs, a microcomputer
is designated as the file server, while in others it is a
computer with a large disk drive and specialized software.
Some file servers also offer other resources such as gateways
and protocol conversion.
Filter :
Process limiting the computation, display and printing to
specified information.
Finger : An Internet software tool for locating people on other
Internet sites. Finger is also sometimes used to give access
to non-personal information, but the most common use is to see
if a person has an account at a particular Internet site. Many
sites do not allow incoming Finger requests, but many do.
Fire Wall :
A combination of hardware and software that separates a
Network into two or more parts for security purposes.
Flame :
Originally, "flame" meant to carry forth in a passionate
manner in the spirit of honorable debate. Flames most often
involved the use of flowery language and flaming well was an
art form. More recently flame has come to refer to any kind of
derogatory comment no matter how witless or crude.
Flame War :
When an online discussion degenerates into a series of
personal attacks against the debaters, rather than discussion
of their positions. A heated exchange.
Flash ROM :
ROM storage able to be updated, deleted or reprogrammed.
Font :
Character style used by a program in order to display or print
a text.
Formal Standards :
Specifications or styles that are approved by
vendor-independent standards bodies, such as the American
National Standards Institute, the International Standards
Organization, the Institute of Electrical and Electronics
Engineers, and the National Institute for Standards and
Technology.
Fragmentation :
File division in physically separated segments in a disk.
Fragmentation is due to file increase in a highly used disk,
thus leading to a lack of sufficient contiguous free space.
Frame Relay :
An International Telegraph and Telephone Consultative
Committee (CCITT) recommendation (I.122) and American National
Standards Institute standard (T1S1). Frame relay is an ISDN
(Integrated Services Digital Network) packet-mode bearer
service that defines a user-to-network interface. The two main
benefits are bandwidth on demand and integrated access. The
standard currently addresses data communications speeds up to
2 Mbps over permanent virtual circuits. By reducing the
network functions performed, frame relay takes advantage of
more robust physical facilities to improve throughput.
FTP :
(File Transfer Protocol) A very common method of moving files
between two Internet sites.
FTP is a way to login to another Internet site for the
purposes of retrieving and/or sending files. There are many
Internet sites that have established publicly accessible
repositories of material that can be obtained using FTP, by
logging in using the account name "anonymous", thus these
sites are called "anonymous ftp servers".
FTP was invented and in wide use long before the advent of the
World Wide Web and originally was always used from a
text-only interface. |
