Understanding Operating System Concepts

What is the main purpose of paging in an operating system?

• To increase the speed of the CPU

• To manage memory by dividing it into fixed-size pages

• To handle input/output operations

• To prioritize processes based on their importance

Which of the following best describes preemptive scheduling?

• A process runs until it voluntarily gives up the CPU

• A process can be interrupted and moved to a steady state

• A process runs until it completes or enters a waiting state

• A process is assigned a fixed time slice

What is a quantum in the context of process scheduling?

• The total time a process takes to execute

• A fixed time slice allocated to a process

• The time a process waits in the queue

• The time a process spends in the blocked state

In non-preemptive scheduling, when does a process switch states?

• When it is interrupted by a higher priority process

• When it completes or enters a waiting state

• When it receives a time slice

• When it is starved of resources

What is burst time in the context of CPU scheduling?

• The time a process spends waiting for resources

• The time a process has control of the CPU

• The time a process is in the ready state

• The time a process is blocked

What does it mean for a process to starve in an operating system?

• It is given too much CPU time

• It is constantly deprived of necessary resources

• It is terminated unexpectedly

• It is in the running state for too long

What is the role of low-level scheduling in an operating system?

• To manage memory allocation

• To assign a processor to a task based on priority

• To handle user input and output

• To manage file systems

What information is contained in a Process Control Block (PCB)?

• Only the process ID

• All data needed for a process to run

• Only the process's memory usage

• Only the process's priority level

Which of the following is NOT a process state?

• Running

• Ready

• Blocked

• Terminated

What is the main characteristic of the round-robin scheduling algorithm?

• It assigns processes based on priority

• It uses time slices assigned to each process in a job queue

• It allows processes to run until they complete

• It only schedules processes in the ready state
