MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Processor scheduling is the allocation of a computer’s processor power to specific tasks. The practice uses the term “scheduling” because it assigns a specific percentage of time the processor is running to individual tasks.

Detailed explanation-2: -CPU scheduling is a process of determining which process will own CPU for execution while another process is on hold. In Preemptive Scheduling, the tasks are mostly assigned with their priorities. In the Non-preemptive scheduling method, the CPU has been allocated to a specific process.

Detailed explanation-3: -The short-term scheduler (also known as the CPU scheduler) decides which of the ready, in-memory processes is to be executed after a clock interrupt, an I/O interrupt, an operating system call or another form of signal.

Detailed explanation-4: -Scheduling of processes/work is done to finish the work on time. CPU Scheduling is a process that allows one process to use the CPU while another process is delayed (in standby) due to unavailability of any resources such as I / O etc, thus making full use of the CPU.
