  1. 2. Circular version of SCAN disk scheduling algorithm.
  2. 5. A page replacement algorithm that removes the oldest page.
  3. 6. The concept that gives an illusion of very large memory.
  4. 7. The physical device used for permanent data storage.
  5. 8. Moving processes between main memory and disk.
  6. 10. Disk scheduling algorithm that moves the disk arm in one direction servicing requests.
  7. 12. Dividing memory into fixed-size blocks.
  8. 13. Selecting a page to remove from memory.
  9. 14. The smallest unit of memory in paging
  10. 15. A page replacement algorithm that removes the least recently used page.
Down
  1. 1. Loading pages into memory only when they are required.
  2. 3. A technique allowing shared pages until they are modified.
  3. 4. Excessive paging that degrades performance.
  4. 5. A fixed-size block in physical memory.
  5. 9. The table that maps logical addresses to physical addresses.
  6. 11. Memory allocation where a process occupies a single continuous block.
