Differences flow with proficiency. But Multiprogramming has lesser

Differences betweenMultiprocessing and Multiprogramming:1.       Definition of Multiprocessing andMultiprogramming: Multiprocessing is a general term which means handlingnumerous processes at once using multiple central processing units. On theother hand Multiprogramming means to run instances from several programs atsame time using only one central processing unit.2.

       Number of CPU Utilization:Multiprocessing needs multiple CPUs to operate a task. But Multiprogrammingrequires single CPU for all the operations.3.

       Parallel Processing: Multiprocessingauthorizes parallel processing to handle corresponding processessimultaneously. On the contrary, Multiprogramming depends on context switchingto instantaneously handle multiple programs. It can’t process multipleprocesses concurrently rather it only processes one process at once and otherprocesses wait in the queue.

Andwhen the current process is finished, the system start executing the nextprocess from the queue. 4.       Processing time: Multiprocessingrequires a smaller amount to perform all the operations. But Multiprogrammingtakes longer time to process all the tasks than multiprocessing.5.       Efficiency: Multiprocessing helps tocreate smooth coordination between computer system and devices and eases theworking flow with proficiency. But Multiprogramming has lesser efficiency indoing that.

6.       Cost: Generally, Multiprocessingoperating systems are a bit pricey than the other systems because of themultiple number of processors. On the other hand, Multiprogramming operatingsystems are much cheaper than Multiprogramming systems since each system hasonly one processor.7.       Clock speed rate: The main objective tobuild a Multiprocessing system is to perform tasks at higher clock speed rate.

But to perform Multiprogramming, a processor of medium to high clock speed rateis required.8.       Performance: A Multiprocessingoperating system is built for the purpose of handling high speed mathematicalcomputations what a multiprogramming operating system cannot do.9.       Task Allocation: Multiprocessingdistributes multiple jobs to multiple processing unit so that the system canexecute tasks concurrently. But Multiprogramming cannot do the allocationbecause of having only one processing unit.

10.   Memory Sharing: In Multiprocessingoperating system, primary memory and peripherals can be shared by multipleprocessors which immensely increases the memory reading writing speed. On theother hand, only one processor can access the primary memory and peripherals inMultiprogramming operating system.11.   Operating System: Multiprocessing isapplied in parallel operating systems whereas Multiprogramming is utilized inbatch operating systems.12.

   Developers: Multiprocessing is relatedto kernel designers. However, Multiprogramming is related to application designers.13.   Example: Now-a-days, most of thecomputers are based on multiple processors. In market term, these systems arecalled multi-cored system.

Intel Core i3, Core i5, Core i7 etc. are the bestexamples of multiprocessing system. Conversely, multiprogramming systems arebit of old now because of lesser efficiency. They are called single-coresystem.

Intel Pentium 3, 4, Celeron etc. are the example of multiprogrammingsystem.
