Describe FCFS Scheduling algorithm ?, Basic Computer Science

Assignment Help:
FCFS algorithm also known as:
• First-In-First-Out (FIFO)
• Run-Until-Done
• Run-to-Completion
• Possibly, First-Come-First-Served algorithm is the easiest scheduling algorithm is the simplest scheduling algorithm. Processes are transmitted according to their advent time on the ready queue. Being a nonpreemptive discipline, one time a process has a CPU, it runs to end. The FCFS scheduling is fair in the proper sense or human sense of fairness but it is unfair in the sense that extended jobs make short jobs wait and insignificant jobs make important jobs wait.
• FCFS is more expected than most of other schemes since it offers time. FCFS scheme is not helpful in scheduling interactive users because it cannot guarantee good response time. The code for FCFS scheduling is easy to write and understand. One of the major drawbacks of this scheme is that the standard time is often quite long.
• The First-Come-First-Served algorithm is hardly ever used as a master scheme in modern operating systems but it is frequently embedded inside other schemes
