Question Text​

  • No, each thread can access every address from the virtual address space

  • Only the heap is shared

  • Only the heap and the read-only zones are shared

Feedback​

Each thread has the same perspective on the system memory - it thinks it owns it all. Therefore, it can perform pointer arithmetic to access every memory address.
