What is the purpose of a web browser's cache?

• A. Cache stores data on the server.
• B. Cookies store web page history.
• C. Cache saves copies of visited pages to speed up loading.
• D. Cache stores recently loaded resources to speed up repeated visits.

Answer: (D)

The browser cache is meant to store recently loaded resources locally so that returning to the same site is faster. When you visit a page, the browser saves things like images, CSS, and JavaScript. On a later visit, it can reuse those local copies instead of downloading them again, which speeds up loading and saves data. This makes browsing feel quicker because repeat visits don’t start from scratch every time. While some caching can involve whole pages, the essential idea is keeping the individual resources nearby to speed up repeated visits. Cache controls (expiration, revalidation) decide when a cached copy is still good or when fresh data should be fetched. You can clear the cache if you want to force loading new content.
