Answer #1

Priority Scheduling	Round-Robin (RR)
Priority Scheduling executes the processes according to the priority i.e. process with higher priority is executed first.	Round-Robin (RR) executes the processes based upon the time quantum defined i.e. each process is executed for a fixed amount of time.
Priority Scheduling is both preemptive and non-preemptive in nature.	Round-Robin (RR) is preemptive in nature.
The average waiting time and average response time is unknown beforehand.	The average waiting time for given set of processes is quite small and depends on the time quantum.
It is easy to implement and best suited for real time operating systems.	It is quite easy to implement RR in any system.
The problem of blocking of a process can be solved using aging.	Each process is executed and every user feels that his work is being done as the CPU gives equal amount of time to each process.

Java program The round-robin scheduling problem: using queue There are n processes in a queue. Each process has namei and timei. The round-robin scheduling handles the processes in order. A round-robin scheduler gives each process a quantum (a time slot) and interrupts the process if it is not completed by then. The process is resumed and moved to the end of the queue, then the scheduler handles the next process in the queue. For example, we have the following queue...
