Write in brief on UNIX file structure. UNIX considers every file to be a sequence of 8-bit bytes no interpretation of these bits is made by the operating system. This system pr
We will brie?y introduce paging to ?nish off this lecture. When a process is loaded, not all of the pages are immediately loaded, since it's possible that they will not all be need
