Question

A Process Control Block(PCB) does not contain which of the following :

a) Code
b) Stack
c) Heap
d) Data
e) Program Counter
f) Process State
g) I/O status information
h) bootstrap program

Answer 1

A Process Control Block (PCB) is a data structure used by operating systems to manage and track the progress of a running process. It contains various pieces of information about the process, such as process state, program counter, code, data, stack, heap, I/O status information, and bootstrap program. Therefore, it does not exclude any of the given options.

Step-by-step explanation:

A Process Control Block (PCB) is a data structure used by operating systems to manage and track the progress of a running process. It contains various pieces of information about the process, such as:

• Process State: This represents the current state of the process, such as ready, running, or blocked.
• Program Counter: This points to the memory address of the next instruction to be executed by the process.
• Code: This refers to the actual instructions of the program being executed.
• Data: This includes the variables and data used by the program.
• Stack: This is used to manage function calls and local variables.
• Heap: This is a region of memory used for dynamic memory allocation.
• I/O status information: This tracks the status of any input/output operations being performed by the process.
• Bootstrap program: This is the initial program that is loaded when the operating system starts.

Therefore, a Process Control Block (PCB) does not contain none of the options from the given list.
