The question may more appropiatley
be ask "what is meant by real time priority levels?"

As loosely define in SVR4 it is one of the two process types recognized by
the process scheduler for active process
es running on a UNIX system.

In other words a (normal) timeshare process would have a process priority of say 100 to 130 and a realtime process would hava e a priority of
say 131 to 160, with the higher
priority process given preference
by the process scheduler. (the system
process which determines which process
runs at which time).

The numerical range will vary depending
on which flavor of UNIX one may be using.

It sort of gaurantees a real time process some cpu time within a given range of time.
