What is the advantage of paging? Creating multiple variable-sized address spaces Physical address space can exceed real physical memory Consolidating multiple disjoint holes in memory into one larger hole Any fixed-size part of address space can be placed into any frame in memory What is the identifier of a fixed-size block of a logical address space? Page table Page frame Page size Page number What is used to move modules within a memory space to avoid fragmentation? Swapping Compaction Linking Paging What causes external memory fragmentation? More memory space being allocated than a single page can hold An entire page frame being allocated regardless of whether that much mem Free memory being separated into small blocks interspersed by allocated m System memory becoming exhausted causing it to be swapped to disk
