Multiprocessing
(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 systems because the operating system must allocate resources to competing processes in a reasonable manner.
(2) Refers to the utilization of multiple CPUs in a single computer system. This is also called parallel processing.

- 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 […]
- multisystem
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 […]
- Multithreading
The ability of an operating system to execute different parts of a program, called threads, simultaneously. The programmer must carefully design the program in such a way that all the threads can run at the same time without interfering with each other.
