Final answer:
A single shared ready queue in operating systems has pros including efficiency, fairness, and low overhead, but also cons such as lack of prioritization and potential starvation.
Step-by-step explanation:
A single shared ready queue is a scheduling algorithm used in operating systems where all processes are placed in a single queue and are serviced by the CPU. There are several pros and cons to using a single shared ready queue.
Pros:
Efficiency: A single shared ready queue simplifies the scheduling algorithm, making it more efficient.
Fairness: Each process has an equal chance of getting CPU time, ensuring fairness.
Low overhead: There is no need to maintain separate queues, reducing overhead.
Cons:
Lack of prioritization: Processes are not prioritized, which may lead to lower-priority processes waiting for a long time.
Starvation: In some cases, a process may never receive CPU time due to higher-priority processes continually being added to the queue.
