Quality-Of-Service (QoS) is the management of system resources, network or otherwise, to apply greater returns with minimal overhead, providing a measurable increase in performance.^1 ^2 ^3
Application QoS is related to thread management or Interprocess Communication (IPC) management as it relates to hardware and software resource access.
"In the field of computer networking and other packet-switched telecommunication networks, quality of service refers to traffic prioritization and resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priorities to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow."
