Which term describes a browser's local copy of information used to speed up access to resources?

• A. Cookie
• B. Cache
• C. History
• D. Bookmark

Answer: (B)

Caching is the mechanism browsers use to speed up access by keeping a local copy of resources. When you visit a page, the browser downloads elements like images, scripts, and stylesheets and stores them in a cache on your device. If you return to that page or another page that uses the same resources, the browser can load them from the local cache instead of fetching them again from the network, which makes loading faster and reduces data usage. The cache is managed automatically, and servers can control how long items stay cached through headers; if something has changed, the browser may fetch an updated version. This is different from cookies (data used for sessions and preferences), history (record of pages you've visited), and bookmarks (saved links to revisit later). So the browser’s local copy that speeds up resource access is the cache.
