Who controls the process control block(PCB)?

Recentemente, I have learnt about kernel and find a question that who controls the process control block(PCB)?The kernel or the process itself? Does it differ in different platform (windows/Linux)? Tão longe, I know PCB is controlled in hardware, but I can't get to the right answer.

OS tracks all necessary information about each process running in the system in PCB. Process Control Block is a data structure representing a process in the OS.

Process control Block PCB is specially defined in the core of the OS for each process.

Por que a almofada SMT caiu facilmente ao soldar as placas PCB?

I am a buyer in a telecom company. Recentemente, an important order of SMT PCBA is delayed due to insophiscated production of a supplier. I am thinking about replace it and just very puzzled about how did their SMT pad fall off easily when soldering the PCB boards. That slows down the whole process.

Como você monta componentes eletrônicos no chassi de um veículo com segurança?

I want to implement a control system I designed for a light electric motorbike. I would like to mount it as professionally as possible on the chassis. It consists of a power system pcb and a SAMC21 development board which I’ll merge later once this all works properly. I have tried screwing it directly on the aluminium chassis but have found that shocks and vibrations from the horn disturbed the system or even destroyed it upon large shocks. Is there a specific way car and motorcycle manufacturers mount their electronics to make their system as robust as possible?

Cada processo possui seu próprio PCB ou existe apenas um??

Para meu entendimento, cada processo no sistema operacional contém seu próprio bloco de controle de processo separado. Alguém pode me explicar isso. Cada processo possui seu próprio PCB ou existe apenas um PCB que contém todas as informações de todos os processos??
