Virtual memory uses a portion of secondary storage (like a hard drive or SSD) to act as an extension of physical RAM. This allows the system to run larger applications or more processes than physical memory alone would permit.

Multiple choice
  1. Ensures each process has enough memory to perform job

  2. Ensures each process is followed step by step

  3. Ensures each process is prioritized in importance

  4. It doesnt care

  4. Defragmenter

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Disk Defragmenter rearranges fragmented data on hard drives, consolidating scattered file segments to improve read/write performance. As files are created, modified, and deleted, data becomes scattered across the disk, slowing access times. Defragmentation physically reorganizes this data for optimal performance. (Note: 'seperated' in the question is misspelled).

Multiple choice
