Demand Paging Swapping Segmentation Paging 2/11 Which of the following is not a benefit of using virtual memory? Increased system stability Ability to run larger programs Protection of memory spaces Reduced memory access speed 3/11 The process of copying the entire process image into the swap space is called: Swapping Segmentation Demand Paging Page Replacement 4/11 Which memory allocation algorithm divides memory into fixed-sized partitions to accommodate processes? First-Fit Best-Fit Buddy System Fixed Partitioning 5/11 Which technique allows the execution of a program which is only partially in memory? Contiguous allocation Paging Swapping Fragmentation 6/11 Which of the following is a disadvantage of the Best-Fit memory allocation algorithm? Increased external fragmentation Memory can only be allocated in fixed-size partitions High overhead in searching for a suitable partition Process thrashing due to insufficient memory 7/11 Which statement is true regarding the buddy system for memory allocation? It is based on the concept of fixed partitioning It reduces external fragmentation It is a dynamic storage allocation algorithm It eliminates the need for page replacement 8/11 Which page replacement algorithm suffers from the Belady's anomaly? Least Recently Used (LRU) First-In, First-Out (FIFO) Clock Optimal 9/11 Which technique divides the physical memory into fixed-sized blocks and uses a bitmap to track allocation? Paging Buddy System Fragmentation Segmentation 10/11 Which memory management technique uses secondary memory as an extension of main memory? Demand Paging Swapping Virtual Memory Fragmentation 11/11 Which statement is true regarding internal fragmentation? It occurs when processes remain in memory for too long It is caused by inefficient memory allocation techniques It can be eliminated by using segmentation It results in external fragmentation
