PCB Meaning in Operating Systems
In operating systems, managing processes is crucial. Each process needs a dedicated block of memory to store its state and control information.
The abbreviation 'PCB' refers to this specific data structure used by the operating system kernel.
The correct expansion for 'PCB' in the context of operating systems is Process Control Block.
This block contains vital details such as the process ID, process state (running, waiting, etc.), CPU registers, memory management information, and accounting information.
Therefore, Option B is the correct answer.
