Usually Page Replacement Algorithms have a buffer and pages to put into the buffer. Buffer size is fixed to a value say 4. Now we keep on adding pages into the buffer, If they are already in the buffer we ignore them and go for the next page to be inserted. If they are not … Read more

If the signal handler is already running when another signal comes in, the action is configurable in the sigaction call. solved How are signals handled in Unix?
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 … Read more
