In what way might the first come first served rule be unfair to the customer waiting for service in a bank or hospital?

In what way might the first-come-first-served rule be unfair to the customer waiting for service in a bank or hospital? In a bank, FCFS may be perceived to be unfair by customers who have large accounts. In a hospital, especially in an emergency room, FCFS is probably the exception rather than the rule.

Which scheduling algorithm is best?

The calculation of three algorithms shows the different average waiting time. The FCFS is better for a small burst time. The SJF is better if the process comes to processor simultaneously. The last algorithm, Round Robin, is better to adjust the average waiting time desired.

What is another common name for a FIFO?

First In, First Out (FIFO) is an accounting method in which assets purchased or acquired first are disposed of first. FIFO assumes that the remaining inventory consists of items purchased last. An alternative to FIFO, LIFO is an accounting method in which assets purchased or acquired last are disposed of first.

Are stacks FIFO or filo?

A stack is sometimes referred to as a Last-In-First-Out (LIFO) or First-In-Last-Out (FILO) structure. A queue is sometimes referred to as a First-In-First-Out (FIFO) or Last-In-Last-Out (LILO) structure.

What are the disadvantages of FCFS?

Disadvantages of FCFS The Average Waiting Time is high. Short processes that are at the back of the queue have to wait for the long process at the front to finish. Not an ideal technique for time-sharing systems. Because of its simplicity, FCFS is not very efficient.

How starvation can be avoided?

Random selection of processes for resource allocation or processor allocation should be avoided as they encourage starvation. The priority scheme of resource allocation should include concepts such as aging, where the priority of a process is increased the longer it waits. This avoids starvation.

Is starvation possible in FCFS?

In fcfs everyone gets chance to execute based on there arrival. so no starvation in FCFS.

What will happen when a process terminates?

What will happen when a process terminates? Explanation: When a process terminates, it removes from all queues. All allocated resources to that particular process are deallocated and all those resources are returned back to OS.

Which queue consists of all processes in the system?

Job queue

Which Scheduler speed is fastest?

What are the three levels of scheduling?

Three types of the scheduler are 1) Long term 2) Short term 3) Medium-term..

What is meant by waiting time?

Waiting time is the time interval for which one has to wait after placing a request for an action or service and before the action/service actually occurs. In operations, it is the time between the actual processes.
