We already know paging divides programs into fixed-size pages. However, at some point, it would occur that a program wouldn’t need precisely the whole page. Therefore, it can leave a free partition of the memory, leading to memory with allocated unused spaces. This is precisely how internal … See more In this tutorial, we’ll first discuss the paging technique responsible for memory management in the operating system. Then, we’llpresent the fragmentation problem and its two … See more Paging allows us to store processes in memory in a discontinuous space. To implement this technique, we divide the processes into pages. Pages are blocks of fixed sizes. Similarly, we also divide physical memory into … See more When dividing programs into fixed-size pages, we also divide physical memory into equal size frames.
