A non-profit corporation, established in 1987, whose mission is to advance the use of computer networks to improve research and education. [Source: RFC1392]
Frequently Asked Question [Source: RFC1392]
Fife and Tayside Metropolitan Area Network.
Fawn Book
the document produced for the JNT defining the Simple Screen Management Protocol (SSMP).
See: Fibre Distributed Data Interface
Formerly Further Education Development Agency, now called Learning and Skills Development Agency (LSDA).
Formerly Further Education Funding Council, now called Learning and Skills Council (LSC).
Federal Information Exchange (FIX)
One of the connection points between the American governmental internets and the Internet. [Source: SURA]
Federal Networking Council (FNC)
The coordinating group of representatives from those federal agencies involved in the development and use of federal networking, especially those networks using TCP/IP and the Internet. Current members include representatives from DOD, DOE, DARPA, NSF, NASA, and HHS. See also: Defense Advanced Research Projects Agency, National Science Foundation. [Source: RFC1392]
Fibre Distributed Data Interface (FDDI)
A high-speed (100Mb/s) LAN standard. The underlying medium is fibre optics, and the topology is a dual-attached, counter- rotating token ring. See also: Local Area Network, token ring. [Source: RFC1208]
file transfer
The copying of a file from one computer to another over a computer network. See also: File Transfer Protocol, Kermit, Gopher, World Wide Web. [Source: RFC1983]
File Transfer Protocol (FTP)
A protocol which allows a user on one host to access, and transfer files to and from, another host over a network. Also, FTP is usually the name of the program the user invokes to execute the protocol. The IP version is defined in STD 9, RFC 959. See also: anonymous FTP, FTAM. [Source: RFC1392]

Compare the Unix "Anonymous FTP" (see above) with the UK JNT Network Independent File Transfer Protocol or NIFTP (now almost extinct), also known as "Blue Book" (see above). The Unix commands are "ftp" and "hhcp" respectively.

A protocol, defined in RFC 1288, that allows information about a system or user on a system to be retrived. Finger also refers to the commonly used program which retrieves this information. Information about all logged in users, as well is information about specific users may be retrieved from local or remote systems. Some sites consider finger to be a security risk and have either disabled it, or replaced it with a simple message. [Source: RFC1983]
Federal Information Processing Standard.
See: Federal Information Exchange
A strong opinion and/or criticism of something, usually as a frank inflammatory statement, in an electronic mail message. It is common to precede a flame with an indication of pending fire (i.e., FLAME ON!). Flame Wars occur when people start flaming other people for flaming when they shouldn't have. See also: Electronic Mail. [Source: RFC1392]
See: Four Letter Extended Acronym
See: Federal Networking Council
For Your Information (FYI)
A subseries of RFCs that are not technical standards or descriptions of protocols. FYIs convey general information about topics related to TCP/IP or the Internet. See also: Request For Comments, STD. [Source: RFC1392]
See: Fully Qualified Domain Name
A piece of a packet. When a router is forwarding an IP packet to a network that has a maximum packet size smaller than the packet size, it is forced to break up that packet into multiple fragments. These fragments will be reassembled by the IP layer at the destination host. See also: Maximum Transmission Unit. [Source: RFC1392]
The IP process in which a packet is broken into smaller pieces to fit the requirements of a physical network over which the packet must pass. See also: reassembly. [Source: RFC1392]
A frame is a datalink layer "packet" which contains the header and trailer information required by the physical medium. That is, network layer packets are encapsulated to become frames. See also: datagram, encapsulation, packet. [Source: RFC1392]
Community-based bulletin board system with email, information services, interactive communications, and conferencing. Freenets are funded and operated by individuals and volunteers -- in one sense, like public television. They are part of the National Public Telecomputing Network (NPTN), an organization based in Cleveland, Ohio, devoted to making computer telecommunication and networking services as freely available as public libraries. [Source: LAQUEY]
File Transfer, Access, and Management. The OSI remote file service and protocol. [Source: RFC1208]
See: File Transfer Protocol
Fully Qualified Domain Name (FQDN)
The FQDN is the full name of a system, rather than just its hostname. For example, "venera" is a hostname and "" is an FQDN. See also: hostname, Domain Name System. [Source: RFC1392]
