How do you think multitasking works on 80386?
- 1.0% The processor has several chips that execute commands at the same time. A quantum of time is a fixed time span to measure system performance 15
- 4.9% The processor has a thread mechanism on which the operating system hangs real threads. A time quantum is a fixed quantity, also used as a performance quantity, relative to which the load is redistributed between the threads 76
- 1.5% The processor does not know anything about threads, it only knows about processes that work on individual chips inside the processor, each for a certain time, called a quantum. After the time quantum is worked out, the active chip that executes code 23 changes
- 2.8% The processor does not know anything about threads, it only knows about processes that are strung on the processor thread mechanism. The preemptive multitasking mechanism is the mechanism by which the processor selects the most difficult time to execute in a given quantum 43
- 28.0% The processor knows nothing about threads or processes. It simply executes instructions sequentially, and the operating system independently changes instructions so that they are executed one at a time from each task and thread, emulating thus. parallel 434
- 61.9% The processor knows nothing about threads or processes. It simply executes instructions sequentially, and the operating system independently changes instructions so that they are executed in large groups, for a certain period of time - quantum 959
