meaning of freeze

1. A frieze.
2. To become congealed by cold; to be changed from a liquid to a solid state by the abstraction of heat; to be hardened into ice or a like solid body.
3. To become chilled with cold, or as with cold; to suffer loss of animation or life by lack of heat; as, the blood freezes in the veins.
4. To congeal; to harden into ice; to convert from a fluid to a solid form by cold, or abstraction of heat.
5. To cause loss of animation or life in, from lack of heat; to give the sensation of cold to; to chill.
6. The act of congealing, or the state of being congealed.
7. freeze To lock an evolving software distribution or document against changes so it can be released with some hope of stability. Carries the strong implication that the item in question will "unfreeze" at some future date. There are more specific constructions on this term. A "feature freeze", for example, locks out modifications intended to introduce new features but still allows bugfixes and completion of existing features; a "code freeze" connotes no more changes at all. At Sun Microsystems and elsewhere, one may also hear references to "code slush" - that is, an almost-but-not-quite frozen state. [Jargon File] Frege, Gottlob Gottlob Frege frequency division multiple access frequency division multiplexing frequency division multiplexing FDM The simultaneous transmission of multiple separate signals through a shared medium such as a wire, optical fibre, or light beam by modulating, at the transmitter, the separate signals into separable frequency bands, and adding those results linearly either before transmission or within the medium. While thus combined, all the signals may be amplified, conducted, translated in frequency and routed toward a destination as a single signal, resulting in economies which are the motivation for multiplexing. Apparatus at the receiver separates the multiplexed signals by means of frequency passing or rejecting filters, and demodulates the results individually, each in the manner appropriate for the modulation scheme used for that band or group. Bands are joined to form groups, and groups may then be joined into larger groups; this process may be considered recursively, but such technique is common only in large and sophisticated systems and is not a necessary part of FDM. Neither the transmitters nor the receivers need be close to each other; ordinary radio, television, and cable service are examples of FDM. It was once the mainstay of the long distance telephone system. The more recently developed time division multiplexing in its several forms lends itself to the handling of digital data, but the low cost and high quality of available FDM equipment, especially that intended for television signals, make it a reasonable choice for many purposes. Compare wavelength division multiplexing, time division multiplexing, code division multiplexing.
