Priority Scheduling leads to the risk of starvation: a process is ready, but never is given the processor. Some preemptive priority schedulers therefore reserve a fraction of the processor cycles for use on lower priority queues; some others implement priority aging whereby the priority of a process increases the longer it has been waiting. Discuss the relative advantages and disadvantages of these schedulers versus a preemptive priority scheduler where priorities are fixed, and the analysis of response time of a process need only consider processes at the same and higher priorities (assuming priority inversion is ignored), and where also a process can guarantee that no higher priority process can be pending when this process is executing (i.e. higher priority process execution is atomic with respect to this process.).
What do you understand by “line balancing”? What happens if balance doesn’t exist?
What is starvation? A main problem related to deadlock is starvation. Starvation is the circumstances where process waits indefinitely within the semaphore. Indefinite blocking
