Solutions for reducing page table overhead. Covers larger pages, hybrid paging-segmentation approaches, and multi-level page table structures to minimize memory consumption while managing virtual memory.
Addresses free space management in memory allocation systems. Covers fragmentation, splitting, coalescing, memory headers, free lists, and allocation strategies like best-fit, worst-fit, and first-fit.
Extends virtual memory beyond physical RAM using disk swap space. Discusses present bit, page faults, page-fault handlers, swap space management, and mechanisms for handling memory larger than physical RAM.
Covers hardware-based address translation using base and bounds registers for memory virtualization. Explains dynamic relocation, hardware requirements for memory protection, and OS involvement in virtual memory.
Introduces paging as solution to virtual memory. Covers page tables, address translation, virtual to physical address mapping, page size considerations, and advantages of paging over segmentation.
