Multitasking and Scheduling Quiz

What is multitasking?

• The ability of a computer to carry out more than one task at a time

• The process of deciding which processes should be carried out

• The execution of each process based on scheduling algorithms

• The allocation of resources to a process for a limited time

What is the purpose of scheduling in multitasking?

• To ensure consistent behavior in system delivery

• To maximize system throughput

• To monitor the state of each process

• To ensure processes do not clash

What are the two types of multitasking operating systems?

• High priority and low priority

• Batch, online, and real-time

• Preemptive and non-preemptive

• Flexible and rigid

In preemptive multitasking, when can a process be interrupted?

• While it is running

• When it has switched to a waiting state

• After a fixed time interval

• Once it has completed its burst time

In non-preemptive multitasking, when can a process be interrupted?

• While it is running

• After a fixed time interval

• Once it has completed its burst time

• When it has switched to a waiting state

What is a risk of high priority processes arriving frequently in the ready queue?

• Low priority processes may be starved of resources

• Processes may clash

• The system may become unstable

• The system throughput may decrease

What is a risk of a process with a long burst time running in the CPU?

• Another process with a shorter burst time may be starved of resources

• The system may become unstable

• The system throughput may decrease

• Processes may clash

What does low level scheduling decide?

• Which process should be switched to a waiting state

• Which process should be interrupted while running

• Which process should be allocated resources for a limited time

• Which process should next get the use of CPU time

What are the objectives of low level scheduling?

• Ensure processes do not clash

• Resolve conflicts between processes requiring the same resource

• Ensure consistent behavior in system delivery

• Maximize system throughput, ensure acceptable response time, and maintain system stability

What factors determine the process priority?

• Category, CPU-bound or I/O bound, resource requirements, turnaround time, waiting time, response time, and interruptibility

• Category, CPU-bound or I/O bound, resource requirements, and deadline for completion

• Category, CPU-bound or I/O bound, resource requirements, and interruptibility

• Category, CPU-bound or I/O bound, resource requirements, and memory requirements
