What is a browser cache and why might you clear it?

• A. It stores your saved passwords and cookies.
• B. It permanently deletes all browser history.
• C. It optimizes graphics drivers.
• D. It stores copies of web resources to speed up loading; clearing can fix stale content and protect privacy.

Answer: (A)

A browser cache stores copies of web resources such as images, HTML, CSS, and JavaScript so pages load faster on subsequent visits. By keeping these local copies, the browser can reuse them instead of downloading everything again, speeding up loading and saving bandwidth. Clearing the cache is helpful when a site updates its resources but your browser continues to serve the old, cached versions, causing stale content or display issues. It also helps protect privacy by removing locally stored copies of sites you’ve visited. Saved passwords and cookies aren’t the cache—they’re managed separately (passwords in a password manager or saved feature, cookies as small data files for sessions and preferences). So the cache’s main role is storing resource copies to speed up loading, and clearing it forces fresh content and can improve privacy.
