- File allocation table. A table or list maintained by an operating system
to keep track of the status of various segments of disk space used for file
- Floppy disk drive controller. A special-purpose chip and associated
circuitry that directs and controls reading from and writing to a computer's
- One half of a television picture. One complete vertical scan of the
picture, containing 262.5 lines. Two fields make a complete television picture
(frame). The lines of field 1 are vertically interlaced with the lines of
field 2 for 525 lines of resolution.
- First in/first out. A method for processing a queue in which items are
removed in the same order they were added.
- Atomic components that provide the basic building blocks for processing
data. Under the WDM Stream architecture, also known as a functional device or
multimedia processing driver. Each filter's capability is described in part by
a number of connection points called pins. Each pin can consume, produce, or
both consume and produce a data stream such as digital audio. Specialized
tasks can be solved by connecting filters by way of their pins into a
topology—for example, to play filtered and mixed audio. Under WDM, a filter is
implemented as a kernel-mode entity that is a device object usually
implemented by a kernel driver. Under ActiveMovie, a filter is a User-mode
entity that is an instance of a COM object, usually implemented by a DLL.
- Frames per second.
- A single screen-sized image that can be displayed in sequence with other
slightly different images to create animated drawings. A video frame consists
of two interlaced fields of either 525 lines (NTSC) or 625 lines (PAL/SECAM),
running at 30 frames per second (NTSC) or 25 frames per second (PAL/SECAM).
Film runs at 24 frames per second.
- full duplex
- In terms of data flow, indicates bidirectional data flow.
- full-motion video
- Video reproduction at 30 frames per second (NTSC-original signals) or 25
frames per second (PAL-original signals). See also frame.
