CPU Scheduling: CPU scheduling is a process that allows one process to use the CPU while the execution of another process is on hold (in waiting state) due to unavailability of any resource like I/O(Input Output) etc. thereby making full use of CPU....
Scheduling Algorithm is divided into mainly 2 parts. Pre-emptive. Non-pre-emptive. Scheduling algorithms It is the way of selecting the process from the ready queue and putting it into the CPU. According to the degree of multiprogramming, we try...
Before talking about phases of compiler let me try to give an idea of Phases. Phases: Phases are the logically interrelated operation that takes source program in one representation and produces output in another representation. There are two majo...
