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. This is managed with a FIFO queue.

I don't know if you will see this comment Varun but you definitely match with the teaching stature of the Professors who did their PhDs and are now teaching in one of the best unis of America. I saw lectures of OS from University of Massachusetts and you match those videos teaching prowess and sometimes better than them. Wish you lots of luck for your future.
