The Advantages Of End Tables Round Robin Scheduling

The Advantages of End Tables Round Robin Scheduling

Round robin scheduling (RRS) is a scheduling algorithm that gives each process in a system an equal amount of time to run. This is done by dividing the time into equal intervals, called time slices, and giving each process one time slice in turn. Once a process has used its time slice, it is put at the end of the queue and the next process is given a time slice. This process is repeated until all processes have had a chance to run.

RRS is a simple and fair scheduling algorithm that is easy to implement. It is also very efficient, as it does not require any overhead to keep track of the amount of time that each process has used. However, RRS can be unfair to processes that have different processing requirements. For example, a process that requires a lot of processing time may only get a small amount of time to run before it is preempted by another process.

There are several advantages to using RRS:

Simplicity: RRS is a simple and straightforward scheduling algorithm that is easy to understand and implement.
Fairness: RRS gives each process an equal amount of time to run, which is fair to all processes.
Efficiency: RRS is a very efficient scheduling algorithm that does not require any overhead to keep track of the amount of time that each process has used.

There are also several disadvantages to using RRS:

Unfairness to processes with different processing requirements: RRS can be unfair to processes that have different processing requirements. For example, a process that requires a lot of processing time may only get a small amount of time to run before it is preempted by another process.
Convoying: RRS can lead to convoying, which is a situation where a group of processes all wait for each other to finish running before they can continue running themselves. This can lead to a decrease in performance.

Overall, RRS is a simple and efficient scheduling algorithm that is fair to all processes. However, it can be unfair to processes that have different processing requirements and it can lead to convoying. Despite these disadvantages, RRS is still a popular scheduling algorithm due to its simplicity and efficiency.
