Operating Systems Quiz

What is an Operating System?

What is a process? How is it different from a program?

What are CPU scheduling algorithms?

What is the primary function of secondary storage?

• To provide large nonvolatile storage capacity

• To execute instructions immediately

• To store frequently accessed data

• To manage CPU resources

What are the characteristics of solid-state disks?

• Faster than hard disks and nonvolatile

• Slower than hard disks and volatile

• Only used for archival storage

• More expensive than magnetic tapes

What is the difference between symmetric and asymmetric multiprocessing?

• All CPUs are equal in SMP, while one CPU controls others in AMP

• SMP is slower than AMP

• AMP uses more memory than SMP

• SMP is only for single processor systems
