| frame rate |
The rate at which frames, the individual pictures that in sequence create the illusion of motion, are displayed in a film or video. Frame rate is measured in frames per second (fps).
|
| frame relay |
A protocol for sending small packets of data over a network. Frame relay uses packets of variable length, unlike cell relay, and requires less stringent error detection than other forms of packet switching because it is designed to take advantage of the more reliable circuits that have become available in recent years. Frame relay is often used for wide area networks, where it can transmit data at high speed more efficiently than point-to-point services. Frame relay is used with digital lines.
|
| frame relay access device |
(FRAD). A combination of hardware and software that is used to convert communications packets from formats like TCP, SNA, IPX, and others into frames that can then be sent over a frame relay network.

| Frame Technology Corporation |
Developers of FrameMaker desktop publishing program. Frame Technology later was taken over by Adobe.
|
| FrameMaker |
A desktop publishing program developed by Frame Technology Corporation, available for UNIX, Macintosh and Windows.
|
| frames |
On World Wide Web pages, a frame is a bordered area that acts as an independent browser window. There can be a number of frames within the same page, and they can be separately scrolled, linked, and viewed. Sometimes a frame can be used to view an entirely different website without leaving the original site that contains the frame. To view a page that has frames, one must use a WWW browser that supports frames, such as the current versions of Netscape and Internet Explorer.
|
| frames per second |
(fps). A measurement of the speed at which pictures (frames) are displayed in sequence in a film or video. The more frames displayed per second, the smoother the motion appears. Full-motion video uses 30 fps or more.
|
| free software |
Software that is free from licensing fees and has no restrictions on use; it can be freely copied, redistributed, or modified.
|
| Free Software Foundation |
(FSF). A nonprofit organization which promotes the development of free software. The GNU project is one of the best-known activities of the Free Software Foundation.
|
| free space |
Empty space on a hard drive, available for loading programs or data. The description of a program for a new user normally indicates the amount of free space needed to load the program. A program that calls for 4 megabytes of free space will take up 4 megabytes on the hard drive.
|
| free speech online |
A movement promoted by the Electronic Frontier Foundation and other organizations to protect the right to freedom of expression in network communications, and specifically to protest the Communications Decency Act and similar legislation. Some WWW pages have icons on them supporting free speech online.
|
| free storage |
|
| free Web page |
(FWP). There are some World Wide Web sites that offer free Web pages to the general public or a selected group of users. There are other sites that offer a free Web page along with membership.
|
| freenet |
An organization that provides Internet access to the public for free or for a small contribution.
|
| Freenet |
A community-based bulletin board system which is part of the National Public Telecomputing Network (NPTN), a Cleveland, Ohio, organization whose aim is to make computer networking as available as public libraries. Freenets are operated by volunteers and funded by donations.
|
| Freeserve |
A popular UK Internet service provider which has no monthly subscription fee, relying instead on call revenue plus premium rate income for calls to its telephone support lines.
|
| freeware |
Freeware is software that is available free of charge, but which is copyrighted by the developer, who retains the right to control its redistribution and to sell it in the future. Freeware is different from free software, which has no restrictions on use, modification, or redistribution.
|
| freeze |
The condition of a computer when the pointer and everything on the screen is frozen in place, and the computer does not respond to commands; one kind of crash.
|
| frequency |
The number of repetitions per unit time of a complete waveform, from peak to trough; for example, the rate of signal oscillation in sound waves or electric current. Frequencies are measured in cycles per second, or Hertz.
|
| frequency division multiplexing |
(FDM). Using several frequencies on the same channel to transmit several different streams of data, from different sources, simultaneously. A technique used for cable TV.
|
| frequency modulation |
(FM). Encoding a carrier wave by modulating its frequency in accordance with an input signal.
|
| frequency modulation synthesis |
FM synthesis. Synthesizing musical sounds by using one waveform to modulate the frequency of another waveform. FM synthesis is an older technique used on inexpensive sound cards, and has a tinny sound. It is being replaced by wavetable synthesis, which more closely simulates the sounds of acoustic musical instruments.
|
| Frequency Shift Keying |
(FSK). Frequency modulation of a carrier signal by a digital signal, in which changes in frequency represent 0s and 1s.
|
| FRICC |
Federal Research Internet Coordinating Committee. A committee founded to coordinate networking in U.S. Federal agencies. The forerunner of the FNC.
|
| FRICC |
Federal Research Internet Coordinating Committee. The body responsible for coordinating networking among United States federal agencies, which was later replaced by the Federal Networking Council (FNC).
