Which of the following statements are TRUE about Process Control Block (PCB)?
A. The PCB contains information about the process state, such as whether it is running, waiting or terminated
B. The PCB includes the program code and data segments of the process
C. The PCB stores the process’s memory management information, such as page tables and segment tables
D. The PCB is used to track process scheduling information and CPU registers for process execution
Choose the correct answer from the options given below:

Correct option is C

The Process Control Block (PCB) in operating systems is crucial for tracking the state and information of a process. Here are some of the critical components:
1. Process State: Holds the current state of the process (running, waiting, terminated).
2. Memory Management Information: Includes details like page tables and segment tables.
3. Scheduling Information: Tracks process priority and scheduling information.
4. CPU Registers: Stores register values, especially when context switching.
Information Booster:
· Process State: Essential for identifying the current status of a process.
· Memory Management Information: Manages memory allocation and protection.
· Scheduling and CPU Registers: Needed for process scheduling and context switching.
