To describe the benefits of a virtual memory system To explain the concepts of demand paging, page-replacement algorithms, and allocation of page frames

Define virtual memory (VM) and describe its benefits. Illustrate how pages are loaded into memory using demand paging. Apply the FIFO, optimal, and LRU page-replacement algorithms.
