The scale goes from zero to 19 for non privileged users. The default nice level is zero. When a process is started it has a default nice level. The nice level is a number that reflects how nice the process is to the CPU. The nicer the process is to the CPU, the less it interrupts it, and the lower its priority is. Because the process is getting fewer resources from the CPU, it also has lower priority. This means other processes will get more CPU time than it will. If the nice level is less than zero, than it is less nice to the CPU, and demands more resources from it, thus having a higher priority for CPU time. In summary, the higher the nice number, the lower the CPU priority. The lower the nice number, the higher the CPU priority. Let's go to terminal to see how this…
