Task (computing)

Task (computing)

A task is an execution path through address space.[1] In other words, a set of program instructions that are loaded in memory. The address registers have been loaded with the initial address of the program. At the next clock cycle, the CPU will start execution, in accord with the program. The sense is that some part of 'a plan is being accomplished'. As long as the program remains in this part of the address space, the task can continue, in principle, indefinitely, unless the program instructions contain a halt, exit, or return.

  • In the computer field, "task" has the sense of a real-time application, as distinguished from process, which takes up space (memory), and execution time. See operating system.
    • Both "task" and "process" should be distinguished from event, which takes place at a specific time and place, and which can be planned for in a computer program.
