Why does clearing cache help?
Show answer & explanation
Answer: Removes outdated stored files
Removes outdated stored files ✓ — Correct! Cache stores temporary files (images, scripts, pages) for faster reloading. Problems arise when: (1) Cached files become outdated/corrupted—showing old content. (2) Cache grows too large—consuming storage. (3) Bugs in cached code cause errors. Clearing cache forces fresh downloads, often fixing display issues, loading problems, or login bugs. Trade-off: sites reload slower initially until cache rebuilds!
Increases internet speed — Wrong. Clearing cache doesn't speed up internet—it removes locally stored files, forcing fresh downloads (initially slower). It fixes issues from corrupted cache.
Fixes hardware problems — Wrong. Cache is software-level temporary storage. Clearing it resolves corrupted or outdated cached files, not hardware issues.
