I wanted to know if an Operating System is a process I cannot find the correct answer about this problem so maybe over here i will find something that might help me for exam that i have tomorrow.
Waiting for answer ...
What underlays an Operating System is a kernel, which is a bunch of low level, routines that manage the memory and other parts of the computer. The kernel has processes and threads that help the kernel accomplish this task.
Thus, the answer to your question is that no, the Operating System is not just one unique process. It is a bunch of processes managed by the kernel that underlay the more abstract concept of what an Operating System is.
