Multithreaded programming vs multiprocess

Answer 1

Multitasking is a method for multiple tasks to share a single resource, like a CPU. This is usually accomplished in software via special programming.

Multiprocessing is the use of multiple CPUs in the same computer and the method of splitting tasks between them. This is usually done with hardware on the motherboard.

Answer 2

Basically multi-tasking is related with the OS & hyper-threading with the processors. Multi-tasking means running several tasks simultaneously on processor.But actually OS(operating system) divides the processor-time between various processes or tasks such that it appears that more than one process is running on processor. But in hyper-threading the processor is divided into 2 different sections & each section appears as a different processor to the OS. So, OS is made to believe that there are 2 processors installed in the system.

Answer 3

Multitasking is the ability to run multiple processes or tasks (either with one processor or multiple processors). Multiprocessing refers to using more than one processor along with the ability to allocate tasks to multiple processors.

Multi-processing is where you have multiple processes/applications that run in parallel whereas multi-tasking is where the code is split into separate blocks, which are executed in parallel.

Whether these separate tasks/processes are run on separate processors depends upon the number of processors installed on the system.

Answer 4

Multiprocessing / multitasking Multiprocessing is the use of two or more processors in a single computer. to acheive greater throughput, economy of scale and increased reliability.Most multiprocessing systems use symmetric multiprocessing, SMP, (as opposed to asymmetric) where all processes share the processing load equally. Multitasking on the other hand is best explained by first defining what multiprogramming is. Multiprogramming is used to ensure the best effecient use of the CPU. Whenever a CPU is processing a program, which is loaded in memory, and it must wait for resources or I/O then it will sit idly which is a waste of the CPU. Multiprogramming will store a number of 'jobs' in a queue and whenever the CPU is waiting for I/O etc while executing a particular job, it will immediately open the next job in the queue and process that job until such time as it must wait again, and then it can select the next job in the queue or return to the previous job. In this way the CPU idle time is reduced. Multitasking is a logical extension of multiprogramming in that instead of waiting for a process to reach a stage where it must wait for I/O or some resource, it schedules time for each process that is loaded into memory, such that each process appears to the user to be running at exactly the same time.Another name for multitasking is timesharing.

Answer 5

Distinguish between multi programming and multi processing?

Answer 6

multiple tasking is that in which more than one tasks are are processed in a single cpu . but when a single task is is going on in a single cpu it single tasking
