Define the “turn-around” time of a user job Turn- around time is total time taken to execute the job.
A- Consider a computer system that provides a virtual memory space that consists of 8 pages. The physical memory contains 4 pages where the page size is 4Kbytes. Assume that at sp
The term IPC (Inter-Process Communication) defines several paths by which different process executing on some operating system interact between each other.
Now, let us discuss two related algorithms for deciding which pages to evict. The clock algorithm is one of the most popular choices. It works by keeping frames in a circular struc
