MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Definition: FCFS is an operating system scheduling algorithm that automatically executes queued requests and processes by order of their arrival. It supports non-preemptive and pre-emptive scheduling. algorithm. FCFS stands for First Come First Serve.

Detailed explanation-2: -FCFS is also the jargon term for the FIFO operating system scheduling algorithm, which gives every process central processing unit (CPU) time in the order in which it is demanded.

Detailed explanation-3: -The idea of FIFO queuing, also called first-come, first-served (FCFS) queuing, is simple: The first packet that arrives at a router is the first packet to be transmitted. This is illustrated in Figure 6.5(a), which shows a FIFO with “slots” to hold up to eight packets.

Detailed explanation-4: -FCFS stands for First Come First Serve. Round Robin is a scheduling algorithm in which the process executes for a fixed CPU quantum time then the next process gets executed then the next process and goes on.
