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 at one given value, thus ruling out any overclocking on motherboards strictly built to the CPU manufacturers specifications. The lock is hard wired into the CPU and is very difficult to overcome.
- 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.
The ability to execute more than one task at the same time, a task being a program. The terms multitasking and multiprocessing are often used interchangeably, although multiprocessing implies that more than one CPUis involved. In multitasking, only one CPU is involved, but it switches from one program to another so quickly that it gives […]
