Understanding Scheduling Algorithms

What is a key characteristic of pre-emptive scheduling?

• Processes cannot be interrupted while running.

• Processes are controlled by a quantum (set time).

• Processes are allocated resources and a "burst time".

• It is a rigid form of scheduling.

In non-preemptive scheduling, what happens to processes with long "burst times"?

• They can be interrupted to allow other processes to run.

• They can leave other processes "starved" of resources.

• They are controlled by a quantum.

• They are given higher priority.

Which type of scheduling is described as more flexible?

• Non-preemptive scheduling

• Pre-emptive scheduling

• Low-level scheduling

• High-level scheduling

What is the main objective of low-level scheduling?

• To allocate resources based on burst time.

• To maximize system throughput and ensure system stability.

• To control processes using a quantum.

• To ensure processes cannot be interrupted.

Which scheduling type can lead to low-priority processes being "starved" of resources?

• Non-preemptive scheduling

• Pre-emptive scheduling

• Low-level scheduling

• High-level scheduling

In which scheduling type are processes allocated a "burst time"?

• Pre-emptive scheduling

• Non-preemptive scheduling

• Low-level scheduling

• High-level scheduling

What does low-level scheduling decide?

• Which process should be terminated.

• Which process should next get the use of CPU time.

• How to allocate memory to processes.

• How to manage input/output operations.

Which scheduling type is described as a rigid form of scheduling?

• Pre-emptive scheduling

• Non-preemptive scheduling

• Low-level scheduling

• High-level scheduling

What is a potential downside of pre-emptive scheduling?

• Processes cannot be interrupted.

• It is less flexible.

• Low-priority processes can be "starved" of resources.

• It does not use a quantum.

What is one of the objectives of low-level scheduling?

• To ensure response time is acceptable.

• To allocate a "burst time" to processes.

• To prevent process interruption.

• To control processes using a quantum.
