OS11-QUIZ

Which of the following is NOT one of the environments where different scheduling algorithms are needed?

• Batch

• Interactive

• Real time

• Distributed

What is primarily optimized by scheduling algorithms in different application areas?

• The type of operating system

• The goals of the system

• The speed of the processor

• The size of the memory

Why are nonpreemptive algorithms or preemptive algorithms with long time periods often acceptable in batch systems?

• They require constant user interaction

• They reduce the number of process switches

• They are easier to implement

• They are less expensive

In which type of systems are batch scheduling algorithms still widely used?

• Real-time systems

• Interactive systems

• Business systems for periodic tasks

• Systems requiring immediate user feedback

Why is preemption essential in environments with interactive users?

• To increase the CPU usage

• To allow one process to use the CPU indefinitely

• To prevent one process from monopolizing the CPU

• To reduce the efficiency of the system

What is the primary reason preemption is needed in server environments?

• Servers are less powerful than personal computers

• Servers need to run without interruptions

• Servers serve multiple users who are in a hurry

• Servers only run one program at a time

What distinguishes real-time systems from interactive systems?

• Real-time systems run arbitrary programs

• Real-time systems are less efficient

• Real-time systems run programs that are intended to further the application at hand

• Interactive systems are designed for single-user scenarios

What is a potential issue with interactive systems?

• They cannot run continuously

• They only serve a single user

• They may run arbitrary programs that are not cooperative

• They are specifically designed for real-time applications

What is a common goal for all scheduling systems in computing?

• Maximizing jobs per hour

• Responding to requests quickly

• Giving each process a fair share of the CPU

• Avoiding data loss

Which goal is specific to batch systems in scheduling algorithms?

• Proportionality

• Throughput

• Fairness

• Predictability
