$9\mathrm{.}5$ VM as a Tool for Memory Protection

Any modern computer system must provide the means for the operating system to control access to the memory system. Mark the following items as "True" or False"

A user process should not be allowed to modify its read$-$only code section.

Nor should it be allowed to read or modify any of the code and data structures in the kernel.

It should not be allowed to read or write the private memory of other processes, and parties explicitly allow it $($via calls to explicit interprocess communication system calls$).$
