Why is PCB labelling bare part number versus assembled part number?

When I audit a supplier, I find that they label PCB bare part. Why do they do that and what is the advantages?

The bare circuit board may be assembled on different levels. A cheaper level of the board may have some missing parts that go into a final product at a cheap level. Some boards with special features tend to face the same problems, too. Label part numbers to help identify this problem.

By the way, the assembled board might have a stick-on label with the final assembly number.

What Others Are Asking

Does each process have its own PCB or there is just one?

To my understanding, each process in the operating system contains its own separate Process Control Block. Can someone explain this to me. Does each process have its own PCB or is there just one PCB that contains all the information for all the processes?
