Test: Task Swapping Methods - Question 1

Which task swapping method does not require the time critical operations?

Detailed Solution for Test: Task Swapping Methods - Question 1

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

Test: Task Swapping Methods - Question 2

Which task swap method works in a regular periodic point?

Detailed Solution for Test: Task Swapping Methods - Question 2

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.

Test: Task Swapping Methods - Question 3

Which of the following determines the next task in the time slice method of task swapping?

Detailed Solution for Test: Task Swapping Methods - Question 3

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.

Test: Task Swapping Methods - Question 4

 Which of the following can be used to distribute the time slice across all the task?

Detailed Solution for Test: Task Swapping Methods - Question 4

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.

Test: Task Swapping Methods - Question 5

 What do a time slice period plus a context switch time of the processor determines?

Detailed Solution for Test: Task Swapping Methods - Question 5

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.

Test: Task Swapping Methods - Question 6

 Which can increase the number of task switches?

Detailed Solution for Test: Task Swapping Methods - Question 6

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

Test: Task Swapping Methods - Question 7

 Which mechanism is used behind the Windows 3.1?

Detailed Solution for Test: Task Swapping Methods - Question 7

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

Test: Task Swapping Methods - Question 8

 Which of the following provides an illusion of multitasking?

Detailed Solution for Test: Task Swapping Methods - Question 8

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

Test: Task Swapping Methods - Question 9

Which task method follows a currently running task to be stopped by a higher priority task?

Detailed Solution for Test: Task Swapping Methods - Question 9

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.

Test: Task Swapping Methods - Question 10

 Which of the following requires programming within the application?

Detailed Solution for Test: Task Swapping Methods - Question 10

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.
