Question

What are the major components of a process image?

1) Registers
2) Program Counter
3) Stack
4) Heap

Answer 1

The major components of a process image are registers, program counter, stack, and heap.

Step-by-step explanation:

The major components of a process image are:

1. Registers: These are small memory locations within the CPU that store data for quick access. They are used to store intermediate results, function arguments, and other temporary data.
2. Program Counter: This is a register that keeps track of the next instruction to be executed in a program. It points to the memory address of the instruction in the program being executed.
3. Stack: This is a region of memory used for local variables and function call information. It grows and shrinks as functions are called and return.
4. Heap: This is a region of memory used for dynamic memory allocation. It is used for storing data that persists beyond the lifetime of a single function or block.
