What is Priority scheduling? - Question & Answer Book

 

Answer:- Priority scheduling is a more general case of SJF, in which each job is assigned a priority and the job with the highest priority gets scheduled first. (SJF uses the inverse of the next expected burst time as its priority – The smaller the expected burst, the higher the priority.) Note that in practice, priorities are implemented using integers within a fixed range, but there is no agreed-upon convention as to whether “high” priorities use large numbers or small numbers. The book uses low numbers for high priorities, with 0 being the highest possible priority.
