Which term is a small file that stores information from a web session on the client machine for later use?

• A. CSS
• B. CSRF
• C. Cookie
• D. Database

Answer: (C)

The concept being tested is how browsers remember session information on the user’s device between requests. The term described here is a cookie. A cookie is a small data file stored by the browser on your computer or device. It can hold simple pieces of information like a session identifier, user preferences, or other session state, and this data is sent back to the server with subsequent requests to the same site, so the site can recognize you and restore your state without you re-entering details.

CSS is a styling language that determines how content looks, not how you persist session data. CSRF refers to a security vulnerability—cross-site request forgery—not a storage mechanism. A database is server-side storage used to persist data long-term, not a client-side file kept on your device for session use.
