Week 5

What is the advantage of First Come First Serve (FCFS) scheduling algorithm?

• Prevents starvation of processes

• Maximizes CPU efficiency

• Minimizes average waiting time

• Provides fairness to all processes

What is the disadvantage of Shortest Job First (SJF) scheduling algorithm?

• Minimizes average waiting time

• Provides fairness to all processes

• Increases CPU efficiency

• Causes starvation of shorter processes

What is the advantage of Round Robin (RR) scheduling algorithm?

• Maximizes CPU efficiency

• Provides fairness to all processes

• Minimizes average waiting time

• Prevents starvation of processes

What is the disadvantage of Priority Based (PB) scheduling algorithm?

• Lower-priority processes may starve

• Maximizes CPU efficiency

• Prevents starvation of processes

• Provides fairness to all processes

What is the advantage of Multilevel Queue Scheduling (MQS)?

• Prevents starvation of processes

• Provides separate scheduling for various kinds of processes

• Minimizes average waiting time

• Maximizes CPU efficiency

What are the main goals of process scheduling policies?

• Maximize CPU utilization, minimize idle time

• Maximize idle time, provide quick response times

• Minimize CPU utilization, maximize idle time

• Minimize idle time, provide fair share of CPU's processing time

What is an interrupt handler?

• A special block of code associated with a specific process

• A special block of code associated with a specific memory location

• A special block of code associated with a specific interrupt condition

• A special block of code associated with a specific CPU

What triggers an interrupt handler?

• Signals sent to the CPU from external devices

• None of the above

• Program instructions

• Both A and B

What does the interrupt handler do when an interrupt occurs?

• Determines the cause of the interrupt, services the interrupt, resumes the interrupted program

• Determines the cause of the interrupt, stops the current operations, resumes the interrupted program

• Services the interrupt, stops the current operations, resumes the interrupted program

• Determines the cause of the interrupt, stops the current operations, services the interrupt

What is the purpose of interrupt handlers?

• To wait for the current program to finish

• To deal with important events as they occur

• To maximize CPU utilization

• To minimize idle time
