It can be used to provide approximate answers to a host of questions, such as: What happens to file retrieval time when disk I/O utilization goes up? Does response time change if both processor speed and the number of users on the systemare doubled? How many lines should a time-sharing system have on a dial-in rotary? How many terminals are needed in an on line inquiry center, and how much idle time willthe operators have?The number of questions that can be addressed with a QUEUING ANALYSIS is endless andtouches on virtually every area in computer science.
