What is a demand queue in computer science?
theres a lot of demand in computer science....computer has become the basis of almost all jobs....from marketing to hotel management...everywhere computers are handy...so u need engineers to solve their problems and make programs for them...so theres no doubt about its demand...

My guess is that a demand queue would be a list of pending operations from the processes running on a machine. A processor can only perform one operation at a time, but it does this really fast. Modern processors can perform billions of operations per second, but that is still a limit.





So on a system with a 1GHz processor, the demand queue would probably be much larger than it would be on a system running the same processes with a 3GHz processor.
