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?
  1. Each Process has its own PCB which is usually stored as a structure.
  2. A linked list of PCBs’ is maintained to keep track of all the processes.

Though it may be implemented differently on various operating systems, the basic concept is this much only. Zo, all in all, you might say that there is a process list that consists of PCBs’ of all the processes.

Wat anderen vragen

How much larger should a plated-through hole be than lead diameter to get good solder wetting?

I’m designing a new PCB where I have a whack of connectors that have to line up with the metalwork. There are some problematic connectors. All 4 pins are round. I want to have the holes as small as possible while allowing for good solder adhesion over the full length of the pin. I’m looking for guidance on how much clearance around the component lead I should have in order to get good solder wetting and adhesion.
