Can a single-processor system have no processes ready and no process running?
What will be an ideal response?
In theory, we might have a single blocked process waiting for an I/O completion; when the completion occurs, the blocked process proceeds to the ready state (or even directly to the running state). However, in practice, most architectures require a valid process to execute at all times.Therefore, many operating systems assign a process created by the kernel to execute when no other processes are ready.
