Jan 24, 2022 · A Process Control Block (PCB) is a data structure used by the operating system to store and manage all the information related to a specific process. It acts as a unique identifier for each process within the system, allowing the OS to …

Process Control Block (PCB) is a data structure that contains information of the process related to it. The process control block is also known as a process descriptor or a task control block. The PCBs of the different processes are stored in a process table in the kernel of …

Aug 9, 2023 · The Process Control Block (PCB) in an operating system is a data structure that stores essential information about an individual process or task. It is also known as the Task Control Block (TCB) or Control Block in some operating systems.

Oct 23, 2018 · The operating system allocates the memory to the process to load the process in the main memory. This field of process control block provides the memory allocation in os to a process. This field provides the knowledge of page table, memory limits, and page table employed by the operating system.

Aug 28, 2024 · The PCB allows the operating system to retain control over process execution and guarantee optimal resource utilization inside the system by storing and maintaining critical process-related information.

Diagram of a PCB. Here’s a visual representation of a PCB: Each process has its own PCB stored in the Process Table. 5. How PCB Helps in Context Switching? Context Switching occurs when the CPU switches from one process to another. The current process’s state and register values are stored in the PCB.
