A) Process Management Subsystem
B) Memory Management Subsystem
C) Input/output Management Subsystem
D) All of the above
E) None of these
Correct Answer: B
Solution :
The compiler generates ad-dresses for a virtual address space with a given address range and the machine's memory management unit translates the virtual address generated by the compiler into address locations in physical memory. The compiler does not have to know wherein memory the kernal will load the program for execution. In fact. Several copies of a program can co-exist in memory. All execute using the same virtual addresses but reference different physical addresses. The sub system of kernels and the hard-ware that co-operate to translate virtual to physical address comprise the memory management subsystem.
