Question about Microsoft Windows XP Professional
What is the basic difference between multitasking multiprogramming and multiprocessing
I would have expected that you would be asking the difference between
multithreading and parallel processing, which is simply a matter of using
sequential processor [multithreading] to simulate simultaneous data streams from multiple processors [parallel processing] while the terms you did inquire concerning are various terms of varying complexity which refer to the simultaneous accomplishment of various tasks.
A multithreading processor alternates the application of tasks to alternating clock cycles of the same processor.
A parallel processor has a matrix of multiple processors assigned to diverse tasks with streaming data from each clock cycle of the same processor for the same task.
multitasking simply means the simultaneous accomplishment of multiple tasks by any means including cyber or human.
Multiprogramming is the simultaneous operation of various alogorithms
where none are halted to allow the others to proceed, which process can be accomplished through with either parallel processors or a multithreaded processor.
Prior to the existence of multiple processors in a single CPU (ex. Core Duo) or even Multithreaded Processors [Pentium Four, PPC], certain types of looping algorithmic methods could be applied [and this programmer did apply such] to multiple tasks to create
the appearance that the tasks were accomplished simultaneously.
The latter was more of a Trompe l'Oeil

This are the Operating system types:
As computers have progressed and developed so have the operating systems. Below is a basic list of the different operating systems and a few examples of operating systems that fall into each of the categories. Many computer operating systems will fall into more than one of the below categories.
GUI - Short for Graphical User Interface, a GUI Operating System contains graphics and icons and is commonly navigated by using a computer mouse. See the GUI definition for a complete definition. Below are some examples of GUI Operating Systems.
Multi-user - A multi-user operating system allows for multiple users to use the same computer at the same time and different times.See the multi-user definition for a complete definition for a complete definition. Below are some examples of multi-user operating systems.
Hope this information could help you to solve your problem. Mam/Sir don't forget me to rate me up I really appreciate what grade/ratings you will be given to me, it could help me lot to answer more questions especially in explaining in more detailed. Thanks a lot and God Bless.
