multiprocessing

noun    (Concise Encyclopedia)

Mode of computer operation in which two or more processors (see CPU) are connected and are active at the same time. In such a system, each processor is executing a different program or set of instructions, thus increasing computation speed over a system that has only one processor (which means only one program can be executed at a time). Because the processors must sometimes access the same resource (as when two processors must write to the same disk), a system program called the task manager has to coordinate the processors' activities.
