Linux operating system uses

  • A.Affinity Scheduling
  • B.Fair Preemptive Scheduling
  • C.Hand Shaking
  • D.Highest Penalty Ratio Next

Answer: B

Linux uses fair preemptive scheduling. The kernel gives each runnable task a share of the processor and can preempt a running task when another deserves the CPU, in order to keep tasks treated fairly by priority and past use.

Affinity scheduling ties a thread to a CPU and is not the general Linux policy. Hand shaking is a communication term, and Highest Penalty Ratio Next is a variant of response-ratio scheduling that Linux does not use.
