Splet01. jan. 2024 · A demand-paging system is similar to a paging system with swapping (Figure 9.4) where processes reside in secondary memory (usually a disk). When we want to execute a process, we swap it into memory. Rather than swapping the entire process into memory, though, we use a lazy swapper. A lazy swapper never swaps a page into … SpletDo we need Segmentation and Paging ? Short answer: You don’t –just adds overhead Most Operating systems use “flat mode” –set base = 0, bounds = 0xffffffff in all segment registers, then forget about it Linux x86: One segment for user code, another segment for user data Both segments cover the same virtual address range!
