WebFor service systems with customers directly involved in the process, FCFS is the dominant priority rule True The shortest processing time (SPT) rule minimizes downstream idle time True Johnson's rule is a technique used to sequence jobs through a two-step work sequence. True WebFCFS Scheduling- In FCFS Scheduling, The process which arrives first in the ready queue is firstly assigned the CPU. In case of a tie, process with smaller process id is executed first. It is always non-preemptive in nature. Advantages- It is simple and easy to understand. It can be easily implemented using queue data structure.
