Which concept stores small files with session information on a local computer to be reused later?

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

Answer: (B)

Storing small pieces of session information on the user's machine for reuse later is done with cookies. Cookies are tiny text files that a web browser saves locally and sends back to the same site with subsequent requests. They let a site recognize you, remember login status, preferences, and other session data so your experience remains consistent as you move between pages or return later. CSS is a styling language for presentation, not for saving session data. A database stores larger, structured data on a server rather than on the user's device for quick session reuse. A cursor is a database construct used to navigate query results, not to persist small client-side session information. Therefore, cookies are the mechanism described.
