What is the main task of CPU scheduling?

• To manage I/O processes

• To handle user interfaces

• To determine which process will own CPU for execution

• To allocate memory to processes

Which scheduling algorithm is based on the principle of Jobs are executed on first come, first serve basis.

?

• Shortest-Job-Next (SJN) Scheduling

• Priority Scheduling

• Round Robin (RR) Scheduling

• First Come First Serve (FCFS)
  

What is the purpose of Preemptive Scheduling?

• To assign tasks with priorities

• To allocate CPU to a specific process

• To minimize waiting time

• To preempt lower priority tasks and poetize the higher priority

Which scheduling algorithm is known for providing each process a fixed time to execute?

• Multilevel Queue

• Priority Based Scheduling

• Shortest Remaining Time

• Round Robin Scheduling

What is the main concern regarding CPU burst distribution?

• CPU utilization

• Waiting time

• Throughput

• none of the above

Which type of scheduling algorithm is used in batch systems where required CPU time is known in advance?

• Shortest-Job-Next (SJN) Scheduling

• Preemptive Scheduling

• Priority Based Scheduling

• Round Robin Scheduling

Which scheduling algorithm is based on the principle of executing processes based on their priority levels?

• Shortest Remaining Time

• Multilevel Queue

• Round Robin Scheduling

• Priority Based Scheduling

Which scheduling algorithm is known for partitioning the ready queue into separate queues based on foreground and background processes?

• Round Robin (RR) Scheduling

• Priority Scheduling

• Multilevel Queue

• Shortest-Job-Next (SJN) Scheduling
