CPU SCheduling

A system must ensure that the CPU is always busy. What component is responsible for selecting the next process to execute?

• Scheduler
• Processor
• I/O Controller
• Dispatcher

A process executes a set of instructions without performing I/O operations. What is this period called?

• CPU Burst

• Turnaround Time

• Arrival Period

• I/O Burst

An operating system must decide which process to run next based on task priority and arrival time. What is this process called?

• Process management

• Process allocation

• Process scheduling
• Process execution

A running process requests I/O and moves to the waiting state. Which type of scheduling allows this transition?

• Preemptive

• Non-preemptive

• Both Preemptive and Non-preemptive

• Neither

A process currently using the CPU is forced to stop execution because a higher-priority process arrives. What type of scheduling is this?

• Preemptive

• Non-preemptive

• Both Preemptive and Non-preemptive

•  Neither

What is the key difference between preemptive and non-preemptive scheduling?

• Preemptive scheduling is always faster than non-preemptive scheduling.
• Non-preemptive scheduling allows for process interruption.
• Preemptive scheduling is used only in real-time systems.
• Preemptive scheduling can interrupt processes, while non-preemptive scheduling cannot.

A system needs to keep multiple programs in memory at the same time for efficient execution. What is this called?

• CPU Scheduling

•  Multiprogramming

• Dispatcher Switching

• Throughput

A process arrives at the CPU scheduler and is immediately placed in a queue before execution. What is this event called?

• Arrival Time

• Burst Time

• Throughput

• Dispatch Latency

What happens during the I/O burst of a process?

• The process enters a sleep state until the next CPU cycle.
• The process performs input/output operations and waits for their completion.
• The process executes CPU instructions without any interruptions.
• The process terminates and releases all resources immediately.

Which metric measures how efficiently the CPU is utilized?

• CPU speed
• CPU utilization
• Memory usage
• Disk I/O performance
