	Is Multitasking More Efficient?
		Joshua Rubinstein, Ph.D., of the Federal Aviation Administration, and David Meyer, Ph.D., and Jeffrey Evans, Ph.D., both at the University of Michigan, describe their research in the August issue of the Journal of Experimental Psychology: Human Perception and Performance, published by the American Psychological Association (APA).
		To better understand executive control, as well as the human capacity for multitasking and its limitations, Rubinstein, Meyer and Evans studied patterns in the amounts of time lost when people switched repeatedly between two tasks of varying complexity and familiarity.
		Thus, multitasking may seem more efficient on the surface, but may actually take more time in the end.

	Multitasking - Wikipedia, the free encyclopedia
		Computer multitasking - the apparent simultaneous performance of two or more tasks by a computer's central processing unit.
		Derived from the first sense, multitasking is the colloquial term for a human being's simultaneous handling of multiple tasks.
		Media Multitasking could involve using a computer, mp3, or any other media in conjunction with another.

	Computer multitasking - Wikipedia, the free encyclopedia
		Multitasking solves the problem by scheduling which task may be the one running at any given time, and when another waiting task gets a turn.
		Another reason for multitasking was in the design of real-time computing systems, where a number of possibly unrelated external activities needed to be controlled by a single processor system.
		Typically, a multitasking system allows another process to run when the running process hits a point where it has to wait for some portion of memory to be reloaded from secondary storage.

	Computer multitasking
		In computing, multitasking is a method by which multiple tasks may execute, apparently simultaneously, on a single computer processor.
		Multitasking on a single CPU is accomplished by rapidly alternating between several active tasks, also known as processes.
		The first efforts to create multitasking systems took place in the 1960s, although the process was then referred to as "time-sharing".

	Multitasking definition by The Linux Information Project (LINFO)
		In a multitasking system, however, multiple processes are retained in the main memory, which physically consists of RAM (i.e., random access memory) chips, so that whenever one process has to wait, the operating system can immediately allocate the CPU to other processes.
		Preemptive multitasking increases overall system efficiency by freeing up the CPU and other system resources when ordered to by the operating system on a time slice basis or a priority basis so that one application cannot monopolize system resources when they are needed by another program.
		Multitasking is particularly crucial for real time operating systems (such as are used in embedded systems), for which it is necessary to monitor and control multiple external activities with a single processor virtually instantaneously.

	TechOnLine - Embedded Systems and Multitasking Software
		Multitasking has entered the mainstream of embedded systems design, thanks in large part to the combination of more powerful processors and great advances in operating system software by vendors who focus on the size and performance needs of the embedded market.
		Multitasking is particularly useful when a software project has to be divided up among multiple programmers, because each programmer can concentrate on his particular section of code and not really worry too much about how his code with interact with the other sections.
		Multitasking in fact forces the applications designer to break the overall application into multiple pieces, so assigning the multiple pieces to multiple programmers is just the next logical step.

	multitasking
		Under "cooperative multitasking" the running task decides when to give up the CPU and under "pre-emptive multitasking" (probably more common) a system process called the "scheduler" suspends the currently running task after it has run for a fixed period known as a "time-slice".
		Multitasking also means that while one task is waiting for some external event, the CPU to do useful work on other tasks.
		Multithreading is a kind of multitasking with low overheads and no protection of tasks from each other, all threads share the same memory.

	Multitasking :: Multi Tasking (Site not responding. Last check: )
		Multitasking should not be confused with multiprocessing because this usually implies that more than a single CPU is performing the task or tasks.
		In multitasking only a single CPU performs the tasks, switching between the tasks and giving the impression that the tasks are being performed simultaneously, which in effect they are, but by switching rapidly from one task to the other rather than actually performing them simultaneously.
		In multitasking, only one CPU is involved, but it switches from one program to another so quickly that it gives the appearance of executing all of the programs at the same time.

	cooperative multitasking (Site not responding. Last check: )
		Cooperative multitasking requires the programmer to place calls at suitable points in his code to allow his task to be descheduled which is not always easy if there is no obvious top-level main loop or some routines run for a long time.
		Under pre-emptive multitasking, the scheduler must ensure that sufficient state for each process is saved and restored that they will not interfere.
		Thus cooperative multitasking can have lower overheads than pre-emptive multitasking because of the greater control it offers over when a task may be descheduled.
