* Multiuser: A computer system the can handle more then one user at a time. Windows is not a multiuser OS. It can handle only one user at a time. * Multitasking: The ability of an OS to do more then one thing at atime. for instance, you can be downloading a large file and still use another program to do something, like write a book. * Multiprocessing: The chip in new computers is able to do more then one task at a time because there is more then one processing unit on/in the chip.
What is the difference between parallel processing and multiprocessing?
multiprocessing is what men do, and multi tasking is what men cant do
the "-ing" part...
Cooperative multitasking is multitasking tohelp someone else, while peemative multitasking is multiaatsking for yourself.
ALU stands for arithmetic and logic unit. The ALU does complex calculations, so by having two it gets the job done faster. This may not really make a difference if your an average user, although if you do AutoCAD and stuff that requires rendering then it will make a HUGE difference.
unix is a multiuser operating system but widows is a single user operating system.
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.
multitasking: more task execute on sevaral cpumultithreading : sevaral part of one program execution
A symmetric multiprocessing (SMP) system is one in which each processor runs an identical copy of the operating system on each processor. In an asymmetric multiprocessing, system, each processor is assigned a specific tasks. An example of this would be a master- slave relationship between one processor and “the rest”.
Multitasking is being able to do more than one thing at a time. Multiprogramming is using more than one 'language' to accomplish a task.
When a person is task switching, they are working on one thing at a time. If a person is multitasking, they are working on more than one thing at once.
a multiprocessor is a small chip insisde a computer system and a multiprocessing system is a computer that is able to have multiple people running processes on a computer at the same time without affecting other users.
