Answer: A Multiprocessing System is a computer hardware configuration that includes more than one independent processing unit. The term multiprocessing is generally used to refer to large computer hardware complexes found in major scientific or commercial applications. The multiprocessor system is characterized by-increased system throughput and application speedup-parallel processing The main feature of this architecture is to provide high speed at low cost in comparison to uni-processor.
A Multiprogramming
Operating System is system that allows more than one active
user program (or part of user program) to be stored in main memory
simultaneously. Multi programmed operating system are fairly sophisticated. All
the jobs that enter the system are kept in the job pool. This pool consists of
all processes residing on mass storage awaiting allocation of main memory. If
several jobs are ready to be brought into memory, and there is not enough room
for all of them, then the system must choose among them. A time-sharing system
is a multiprogramming system.
