OPERATING SYSTEM QUIZ 2

What is the purpose of a Process Control Block?

• To switch contexts

• To manage process threads

• To store the process state

• To control the CPU scheduler

Which scheduling algorithm is based on the principle of executing the shortest job first?

• Shortest-Job-First Scheduling

• First-Come First-Served Scheduling

• Pre-emptive Scheduling

• Round Robin Scheduling

What is the main function of a CPU Scheduler?

• To manage process threads

• To schedule processes for execution

• To switch contexts

• To store the process state

What is the key difference between pre-emptive and non-pre-emptive scheduling?

• Pre-emptive scheduling is less efficient

• Non-pre-emptive scheduling is more flexible

• Pre-emptive scheduling allows a process to be interrupted

• Non-pre-emptive scheduling is faster

What is the purpose of Process Threads in Process Management?

• To switch contexts

• To manage process scheduling

• To store the process state

• To execute multiple tasks concurrently

What is the purpose of a Round Robin Scheduling algorithm?

• To execute the longest job first

• To execute the shortest job first

• To allocate equal time slices to each process

• To prioritize I/O bound processes

Which scheduling algorithm allows a process to be interrupted and moved to the ready queue?

• First-Come First-Served Scheduling

• Shortest-Job-First Scheduling

• Pre-emptive Scheduling

• Non-pre-emptive Scheduling

What is the purpose of a CPU Scheduler in process management?

Which scheduling algorithm allocates equal time slices to each process?

• First-Come First-Served Scheduling

• Shortest-Job-First Scheduling

• Pre-emptive Scheduling

• Round Robin Scheduling

What is the key difference between I/O bound and CPU bound processes in scheduling?

• I/O bound processes require more CPU time

• CPU bound processes have more I/O operations

• I/O bound processes spend more time waiting for I/O operations

• CPU bound processes have shorter execution times
