Problem

top, by default, lists both columns. I am curious as to what is the difference. I checked out the man pages and cannot figure it out: Priority: Nice value: I understand that Nice value is related to the Kernel's CPU scheduler queue; then what does Priority indicate? Something regarding I/O perhaps?

Error Output

h: PR  --  Priority
      The priority of the task.
