💡 Hint

Common Mistakes

Confusing queues with threads or processors.

Thinking files are involved in scheduling.

Multilevel queue scheduling divides processes into separate queues based on their properties like priority or type.

2fill in blank

medium

Complete the sentence about the scheduling policy in multilevel queue scheduling.

Operating Systems

Each queue in multilevel queue scheduling has its own [1] to decide the order of process execution.

💡 Hint

Common Mistakes

Confusing scheduling algorithm with memory or network terms.

Thinking all queues share the same scheduling method.

Each queue uses its own scheduling algorithm to manage the processes within it.

3fill in blank

hard

Fix the error in the statement about process movement in multilevel queue scheduling.

Operating Systems

In multilevel queue scheduling, processes can [1] between queues during execution.

Cstay

Dswitch

💡 Hint

Common Mistakes

Assuming processes can move between queues like in multilevel feedback queue.

Confusing multilevel queue with other scheduling types.

In multilevel queue scheduling, processes stay in the queue they are assigned to; they do not move between queues.

4fill in blank

hard

Fill both blanks to complete the description of queue priority and scheduling.

Operating Systems

Higher priority queues are scheduled [1] than lower priority queues, and each queue uses [2] scheduling.

Drag options to blanks, or click blank then click option'

Abefore

Bafter

Cround-robin

Dfirst-come-first-served

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up the order of priority scheduling.

Confusing scheduling algorithms used in queues.

Higher priority queues are scheduled before lower priority ones, and each queue can use first-come-first-served scheduling.

5fill in blank

hard

Fill all three blanks to complete the explanation of multilevel queue scheduling characteristics.

Operating Systems

Multilevel queue scheduling divides processes into [1], assigns each queue a [2], and does not allow [3] between queues.

Drag options to blanks, or click blank then click option'

Aqueues

Bpriority

Cmovement

Dtime slices

Attempts:

💡 Hint

Common Mistakes

Thinking processes can move between queues.

Confusing priority with time slices.

It divides processes into queues, assigns each queue a priority, and does not allow movement of processes between queues.
