Detailed explanation-1: -Explanation: The operating system information is not the component of the PCB, so option (d) is the correct answer.
Detailed explanation-2: -A process control block (PCB) stores data about the process, such as registers, quantum, priority, and so on. The process table refers to an array of PCBs, which means that it logically contains a PCB for each of the system’s active processes.
Detailed explanation-3: -Explanation: A Process Control Block (PCB) is a data structure. It contains information related to a process such as Process State, Program Counter, CPU Register, etc. Process Control Block is also known as Task Control Block.
Detailed explanation-4: -PCB contains fields like process ID, process priority, process state, accounting information, list of open files, etc. PCBs are stored in the form of LinkedList in the memory. Process table contains a reference to every process currently being executed in the system.
