Which scheduling is best?
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 the job sequence?
The sequencing of jobs on a single processor with deadline constraints is called as Job Sequencing with Deadlines. You are given a set of jobs. Each job has a defined deadline and some profit associated with it. The profit of a job is given only when that job is completed within its deadline.
How are process scheduling algorithms used in the operating system?
In this blog, we will learn about various process scheduling algorithms used by CPU to schedule a process. But before starting this blog, if you are not familiar with Burst time, Arrival time, Exit time, Response time, Waiting time, Turnaround time, and Throughput, then you should first learn these topics by reading the blog from here.
Why is FCFS not an efficient process scheduling algorithm?
Throughput is not efficient. FCFS suffers from the Convey effect i.e. if a process is having very high burst time and it is coming first, then it will be executed first irrespective of the fact that a process having very less time is there in the ready state.
What do you need to know about process scheduling?
But before starting this blog, if you are not familiar with Burst time, Arrival time, Exit time, Response time, Waiting time, Turnaround time, and Throughput, then you should first learn these topics by reading the blog from here. Also, learn about Preemptive and Non-Preemptive scheduling from here.
When to use the 2MS process scheduling algorithm?
After one cycle, again P1 will be given 2ms, then P2 will be given 2ms and so on until the processes complete its execution. It is generally used in the time-sharing environments and there will be no starvation in case of the round-robin.
