Detailed explanation-1: -First Come First Serve (FCFS) is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival. It is the easiest and simplest CPU scheduling algorithm. In this type of algorithm, processes which requests the CPU first get the CPU allocation first.
Detailed explanation-2: -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.
Detailed explanation-3: -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. FIFO’s opposite is LIFO, last-in-first-out, where the youngest entry or “top of the stack” is processed first.
Detailed explanation-4: -First Come First Serve (FCFS) Its implementation is based on FIFO queue.
Detailed explanation-5: -With first come, first served, what comes first is handled first; the next request in line will be executed once the one before it is complete.
