Most modern operating systems use memory virtualization support provided by the underlying hardware platform to isolate application processes from each other.
Each process has its own virtual address space that is completely independent of the address spaces of other applications. This provides huge benefits to developers. Since the address processes of applications are independent, an application cannot accidentally corrupt the memory of another application. As a result, a failure in one application does not affect the whole system. Since all the other applications keep working, the system can recover by restarting the failing application.
The benefits of memory isolation come at a cost. Since one process cannot access the memory of another, it needs to use a dedicated Application Program Interface (API) for data exchange...
