Telephone Line Problem Callers queue for outgoing lines This system will allow only eight outgoing connections Telephone Line Problem The outgoing telephone lines could be physical as in the original version or virtual as in ATM and the decision of the CAC function would decide the number of connections available. Queues are used in many kinds of software such as Operating systems Queues keep track of processes waiting for a turn in the CPU Simulations In a Laundromat simulation a queue might keep track of loads of laundry waiting for a dryer Graphical user i Dr. Andrew Wallace PhD .
