A communications device that multiplexes (combines) several signals for transmission over a single medium. A demultiplexor completes the process by separating multiplexed signals from a transmission line. Frequently a multiplexor and demultiplexor are combined into a single device capable of processing both outgoing and incoming signals.
A multiplexor is sometimes called a mux and also spelled as multiplexer.
- multiplier lock
The multiplier lock is used by CPU manufacturers to prevent consumers and dealers from overclocking the CPU. When overclocking became mainstream, profit margins for CPU manufacturers lowered because users wouldn’t need to upgrade to a faster processor. When locked, the multiplier–the factor by which the bus speed is multiplied to derive the CPU speed–is stuck […]
- multipoint videoconference
A videoconferencing with more than two sites. In order to connect the two sites a video bridge must be used.
(1) Refers to a computer system’s ability to support more than one process (program) at the same time. Multiprocessing operating systems enable several programs to run concurrently. UNIX is one of the most widely used multiprocessing systems, but there are many others, including OS/2 for high-end PCs. Multiprocessing systems are much more complicated than single-process […]
- multiscanning monitor
A type of monitor that automatically adjusts to the signal frequency of the video display board to which it is connected. Consequently, multiscanning monitors can display images based on almost any graphics display system, including MDA, Hercules, EGA, VGA, and SVGA. In contrast, fixed-frequency monitors respond to only one, or a few, frequencies, so they […]
In video devices, a multisystem is one that is capable of receiving and displaying different video formats. A multisystem TV or VCR for example would be able to display PAL, SECAM, NTSC or any combination. Most multisystem devices also offer dual voltage sources so they can be used almost anywhere in the world.
