A Timely Question.

A Timely Question. Most modern operating systems (O/S) pre-emptively schedule programs. If you are simultaneously running two programs A and B, the O/S will periodically switch between them, as it sees fit. Specifically, the O/S will: Stop A from running Copy A’s register values to memory
