FIFO

First-in First-out: All telephone networks are a trade-off. It’s simply to expensive to build a phone network which will be ready to give everyone dial tone and a circuit if everyone picked up the phone simultaneously and tried to make a call. There are basically two ways of handling calls which cannot be sent on their way- i.e. for which there’s no present available capacity. First, you can "block" the call. This means giving the caller a busy or a "nothing" (also called "high and dry"). Second, you can put the call into a queue. Now you have people waiting in queue, how do you handle them? The most equitable-the way most queues work-is to handle the calls on the basis of First In, First Out.(First call to come in is handled first.) There are other ways of handling calls in a queue-including First In, Last Out, by priority (e.g. which line you came in on and how much it cost, or how high you are in the corporation, etc.)
