Relative ordering given to a process with respect to other processes. System processes have a higher priority than user processes.
A value that the scheduler calculates to determine which process(es) should next run on the CPUs. A process' priority is calculated from its nice value and its recent CPU usage.
A number that determines how often the kernel will run a process. A higher-priority process will run more often and, therefore, will finish faster, than a low-priority process.
A value assigned to a task to determine how frequently it may have access to the CPU or devices.
For Process Control, the relative ranking of a process or process group with respect to the use of CPU and system resources. You can configure this in the Process Control snap-in.
