Mac OS has virtual memory, in the limited sense that a larger fixed address space can be simulated, by storing the entire address space on disc. This size of this address space is

These programs generate the illusion and useful understanding of a unified interface, but deliver significantly more flexibility in the user's capability to change things that suit his or her certain needs. Processes Vs. Threads A process, in the simplest terms, is an executing
