Page Management is an important part of the operating system, which basically makes the memory management of the computer effective and efficient. In modern computer systems, many programs run simultaneously and each program needs to be allocated sufficient memory. As a solution to this problem, Page Management is used, which is a basic component of the virtual memory system. In the Page Management method, instead of loading the entire memory of a program into the main memory (RAM) at once, it is divided into small equal-sized parts, which are called Pages. Similarly, the main memory is also divided into equal-sized blocks, which are called Frames. Each Page can be loaded into any empty Frame, thus increasing the flexibility in memory usage. The biggest advantage of this method is that it eliminates External Fragmentation. Since all Pages and Frames are of the same size, memory waste is reduced. In addition, Page Management makes memory management easier for programmers, becau...
