Definition von multitasking im Englisch Englisch wörterbuch: Present participle of multitask; The practice or capability of handling more than one task at the same time; The simultaneous execution of multiple tasks (programs) under the control of an interrupt-driven operating system; The concurrent execution of multiple programs Mac OS X uses preemptive multitasking Mac OS 8 and 9 use cooperative multitasking; The ability to execute more than one task at the same time, a task being a program; the execution of two or more processes at the same time; The ability to run more than one program at the same time There are different types of multitasking Cooperative multitasking requires a program to be written to allow other programs to access the system In preemptive multitasking, the system can suspend any program to allow other programs access Preemptive multitasking provides better performance, as programs can switch with less overhead The Macintosh and Windows 3 1 use cooperative multitasking Windows 95 and Unix use preemptive multitasking; The ability of a CPU to perform more than one operation at the same time; Windows and Macintosh computers are multitasking in that each program that is running uses the CPU only for as long as needed and then control switches to the next task; (1) (n ) Enabling more than one user to access the same program at the same time (2) (adj ) Characteristic of the concurrent execution of two or more tasks by a computer; A mode of operation offered by an operating system in which a computer works on more than one task at a time; In computer programming, a mode of operation that allows multiple tasks to run concurrently or the interleaved execution of two or more tasks (a unit of programming controlled by the operating system); Working at a computer with multiple programs available at the same time Running multiple application concurrently on the computer allows the user to quickly jump from one program to another without closing and opening applications; The possibility of an operating system to efficiently manage more than one task at a time; The execution of commands in such a way that more than one command is in progress at the same time; Operating system capability that enables two or more tasks, programs, or processes to be interleaved or executed simultaneously; {i} simultaneous operation of several programs by one computer (Computers); The ability to run two or more programs (tasks) on one computer at the same time The tasks take turns using available I/O and CPU cycles; The capability of a computer with a single CPU to simulate the processing of more than one task at a time Multitasking is effective when one (or more) of the applications spends most of its time in an idle state, waiting for a user-initiated event such as a keystroke or mouse click; A mode of operation that provides for concurrent performance, or interleaved execution of two or more tasks; Using your computer to run two or more programmes at once You might, for example, open two documents simultaneously to edit between them and need a spreadsheet open to refer to Macs have had little trouble multitasking, though it was not until Windows Ã«95 that PCÃs became happy with the chore; 1 adj The ability to download software from the Internet while running productivity applications 2 n A multiple process Operating System scheme which relies on computer hardware to efficiently and safely share computer resources between applications See Task Switching; Mode of computer operation in which the computer works on multiple tasks at the same time. A task is a computer program (or part of a program) that can be run as a separate entity. On a single-processor system, the CPU can perform preemptive (also called time slicing or time sharing) multitasking, where it executes part of one program, then switches to another program, and then returns to the first one. On multiprocessing systems, each processor can handle a separate task; - The ability of an operating system to run more than one program, or task, at a time A cooperative multitasking OS, like Windows 95/98, requires one application to voluntarily free up resources upon request so another application can use it A preemptive multitasking OS, such as GNU/Linux, Windows NT/2000 or OS/2, frees up resources when ordered to by the operating system, on a time-slice basis, or a priority basis, so that one application is unable to hog resources when they are needed by another program (Also, see Multithreading and Time-sharing ); Some OSes have built into them the ability to do several things at once This is called multitasking, and has been in use since the late sixties / early seventies Since this ability is built into the software, the overall system will be slower running two things at once than it will be running just one thing A system may have more than one processor built into it though, and such a system will be capable of running multiple things at once with less of a performance hit; The capability of a computer system to process more than one job at a time; The ability of a person to handle several tasks at once; Running several programs at once -- Linux excels at this The kernel switches between processes so quickly that they appear to be running simultaneously; The technique of using several applications programs (tasks) in a computer system or on several terminals in a network at the same time Multitasking can simultaneously work with several programs or interrelated tasks that share memories, codes, buffers, and files; Executing more than one process on a single processor, usually achieved by timesharing under the control of the operating system; The ability of an operating system to run several programs simultaneously and independent from another If a computer only has one CPU, this is achieved by distributing the computing power by a so-called scheduler, running each program for a small amount of time, calculated by special criterions UNIX to some extent Win offer a good multitasking See multithreading also; (n ) Executing many processes on a single processor This is usually done by time-slicing the execution of individual processes and performing a context switch each time a process is swapped in or out, but is supported by special-purpose hardware in some computers Most operating systems support multitasking, but it can be costly if the need to switch large caches or execution pipelines makes context switching expensive in time
preemptive multitasking: multitasking in which the operating system has continuous control over the processor and the programs which the processor executes
