Test: Task Swapping Methods - Computer Science Engineering (CSE) MCQ

Explanation: Time-critical operations are not essential in the time slice mechanism. Time slice mechanism describes the task switching in a particular time slot.

Explanation: The time slicing works by switching task in regular periodic points in time, that is, any task that needs to run next will have to wait until the current time slice is completed.

Explanation: The time slice mechanism can also be used a scheduling method in which the task to run next is determined by the scheduling algorithm.

Explanation: The time slice based system uses fairness scheduler or round robin to distribute the time slices across all the tasks that need to run in a particular time slot.

Explanation: The context switch time of the processor along with the time slice period determines the context switch time of the system which is an important factor in a system response, that is, the time period can be reduced to improve the context switching of the system which will increase the number of task switches.

Explanation: The time period can be reduced to improve the context switching of the system which will increase the number of task switches.

Explanation: The cooperative multitasking mechanism is used the Windows 3.1 but it is not applicable to the real-time operating systems.

Explanation: The cooperative multitasking co-operates between them which provides the illusion of multitasking. This is done by periodically executing the tasks.

Explanation: The pre-emption is an alternative method of the time slice where the currently running task can be stopped or preempted or switched out by a higher priority active task.

Explanation: The cooperative multitasking requires programming within the application and the system can be destroyed by a single program which hogs all the processing power. Therefore, it is not applicable in the real-time operating system.
