Which of the following statements are TRUE about Process Control Block (PCB) ?…

Answer: The correct statements are the ones that say the PCB contains information about the process state, stores memory-management information (such as page tables or segment tables), and is used to track scheduling information and CPU registers for process execution. The statement that the PCB includes the program code and data segments is not correct.

Why the incorrect statement is false:

• The PCB does not contain the process's actual program code or data segments; those reside in the process address space in memory or on disk. The PCB may hold pointers or references to those regions but not the code/data themselves.

Typical contents of a PCB:

• Process identifier and current process state (running, waiting, ready, terminated).

• CPU registers and program counter values needed to resume execution.

• Scheduling information (priority, pointers in scheduler queues, accounting data).

• Memory-management information (base/limit or page table/segment table pointers).

• I/O status and resource allocation information.

Summary:

• True statements describe process state, memory-management information, and scheduling/CPU-register tracking.

• The false statement incorrectly claims the PCB stores the program code and data segments themselves.
