WebKey Differences Between Paging and Segmentation. The basic difference between paging and segmentation is that a page is always of fixed block size whereas, a segment is of variable size.; Paging may lead to internal fragmentation as the page is of fixed block size, but it may happen that the process does not acquire the entire block size which will … Web6 de nov. de 2024 · 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 frames. When executing a process, the CPU converts each page’s logical address to a physical address. general rudolf toussaint
