| | Computer multitasking - Wikipedia, the free encyclopedia |
 | | 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. | | | 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, also known as processes, share common processing resources such as a CPU. |

| | Multitasking: allows multiple processes to run seemingly simultaneously on a single processor |
| | Multitasking can be easily observed in Unix-like operating systems when the X Window System (the standard system for managing GUIs on single computers and on networks of computers) is used. | | | A multitasking operating system is one in which multiple processes, also referred to as tasks, can execute (i.e., run) on a single computer seemingly simultaneously and without interfering with each other. | | | In a multitasking system, however, multiple processes are kept in the main memory (i.e., RAM) so that whenever one process has to wait, the operating system can allocate the processor to other processes. |

| | multitasking - Definition of multitasking by Webster's Online Dictionary |
| | Multitasking also means that while one task is waiting for some external event, the CPU to do useful work on other tasks. | | | 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". | | | A multitasking operating system should provide some degree of protection of one task from another to prevent tasks from interacting in unexpected ways such as accidentally modifying the contents of each other's memory areas. |

| | Johannes Auer: Multitasking als Avantgarde |
| | Orientation 2 Multitasking is not something the human brain is naturally capable of, if what is meant is carrying out two or more tasks with the same degree of attention and efficiency, researchers tell us. | | | Multitasking means that several different programs can be activated simultaneously. | | | It is only through switching the window of attention from one task to the other at rapid intervals that a comparative quality in multitasking is possible for conscious cognitive processes. |

| | pre-emptive multitasking |
| | The tasks under pre-emptive multitasking can be written as though they were the only task and the scheduler decides when to swap them. | | | The length of time for which a process runs is known as its "time slice" and may depend on the task's priority or its use of resources such as memory and I/O. Unix and the Amiga use pre-emptive multitasking. | | | A type of multitasking where the scheduler can interrupt and suspend ("swap out") the currently running task in order to start or continue running ("swap in") another task. |

| | Specifically, the magnitude of the multitasking multiplier is itself a function of the load ratio. | | | Multitasking simply causes expensive capacity to be redirected to the creation of more and more work in process, at the expense of throughput. | | | Thus, a multitasking policy setting of 10, which specifies that the resource must work a maximum of 10 tasks simultaneously at every possible opportunity, is used to model the case of nearly unlimited multitasking. |

| | cooperative multitasking |
| | 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. | | | This contrasts with pre-emptive multitasking where the task scheduler periodically suspends the running task and restarts another. | | | A form of multitasking where it is the responsibility of the currently running task to give up the processor to allow other tasks to run. |

| | Multitasking :: Multi Tasking |
| | 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. | | | Multitasking refers to the capability to perform more than one task at a time. | | | Multitasking should not be confused with multiprocessing because this usually implies that more than a single CPU is performing the task or tasks. |

| | Multitasking Introduction |
| | Multitasking enables a complex job to be implemented by designing separate tasks that operates independently or cooperates. | | | The new concept of deterministic multitasking allows the task to be written like a procedure or process. | | | Each task is simple, but the total collection of tasks enables a complex job to be solved. |

| | Multitasking operating systems have become quite familiar lately, since Microsoft Windows(R) and Unix conquered the growing market of personal computers software. | | | This problem is solved in the so called "supervised cooperative" multitasking, by introducing a watch dog timer, which forces task switching if a task lasts more than a specified amount of time. | | | This article describes a way to develop a set of programming tools, in order to create a multitasking platform, working with virtually any microcontroller available on the market. |

| | Pre-emptive multitasking: Information From Answers.com |
| | Usage: Pre-emptive multitasking is sometimes mistakenly used when the intended meaning is more specific, referring instead to the class of scheduling policies known as time-shared scheduling, or time-sharing. | | | In pre-emptive multitasking, the Operating System kernel can also initiate a context switch to satisfy the scheduling policy's priority constraint, thus pre-empting the active task. | | | Preemptive multitasking creates a time-shared environment in which running programs get a recurring slice of time from the CPU. |

| | Pre-emptive Multitasking is like Co-operative Multitasking in that it allows I/O and delays to cause a task switch, but no task can hog the processor for more than 10ms (default value). | | | We see some applications constructed as a large monolithic program because the author thought multitasking would be hard, but the reverse is true, it saves time and cost. | | | This is why multitasking can be dangerous; the second task might only want the variable occasionally. |
