		In computing, multitasking is a method by which multiple tasks, also known as processes, share common processing resources such as a CPU.
		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.
		In computing, multitasking is a method by which multiple tasks may execute, apparently simultaneously, on a single computer processor.

	Computer multitasking - Encyclopedia, History, Geography and Biography
		Although multitasking techniques were originally developed to allow multiple users to share a single machine, it soon became apparent that multitasking was useful regardless of the number of users.
		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 - Wikipedia
		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".
		Although the original purpose behind the design of multitasking was to allow multiple users to share a single machine, it soon became apparent that multitasking was useful regardless of the number of users.

	Talk:Computer multitasking - Wikipedia, the free encyclopedia
		Preemptive multitasking was tried in the early 1960s, but it turned out to be a lot harder to do reliably than anyone expected.
		I'm pretty sure that cooperative multitasking was a kludge to make multitasking work better by making sure that programs were in a suspendable state when they gave up control.
		Multitasking is a generic term allowing multiple tasks to be run, witout regard to timing.

	Computer multitasking - Wikipedia, the free encyclopedia
		Even on computers with more than one CPU (called multiprocessor machines), multitasking allows many more tasks to be run than there are CPUs.
		When the computer ran a program that needed access to a peripheral, the CPU would have to stop executing program instructions while the peripheral processed the data.
		In a system with preemptive multitasking, a hardware system (not included on many early machines) can "interrupt" a running process, and direct the processor to execute a different piece of code.

	The Digital Research Initiative
		Computers which are capable of "preemptive multitasking" are generally more powerful than those which are simple "multitasking" computers.
		As a rule, most computers are powerful enough to handle preemptive multitasking, at least those made since the mid-1980s, but usually these computers don't have that ability because of the limitations of their operating systems.
		It should be also noted that "preemptive multitasking" is an elusive goal for many operating systems, as very few are able to achieve this ability, Some companies claim their system is preemptive multitasking, when it is really not.

	multitasking -- Britannica Concise Encyclopedia - The online encyclopedia you can trust!
		Multitasking is used to keep all of a computer's resources at work as much of the time as possible.
		While the computer is reading data from a magnetic disk at a fairly limited rate, for example, its powerful central processor can execute at high speed another program that involves extensive calculations but very little input.
		Two programs can be executed on a small computer using a foreground/background system, in which the computer executes the instructions of one program only in between the times it devotes to running another program of higher priority.

		A computer program or routine is described as reentrant if it is designed such that a single copy of the program's instructions in memory can be shared by multiple users or separate processes.
		The key to the design of a reentrant program is to ensure that no portion of the program code is modified by the different users/processes, and that process-unique information (such as local variables) is kept in a separate area of memory that is distinct for each user or process.
		Reentrant programming is key to many systems of multitasking.
