What are cookies used for in a web browser?

• B. Cookies are used to power the device hardware.
• C. Cookies store small data on the client to manage sessions and preferences.
• D. Cookies delete data automatically after a day.

Answer: (C)

Cookies are small pieces of data that a web browser stores on your computer to remember information between visits. This lets websites manage your session, such as keeping you logged in as you move around a site or after you refresh the page, and remember preferences like language, theme, or items in a shopping cart. The data is sent back to the site with each request, so the server can recognize you and provide a personalized experience. The other choices don’t fit because cookies don’t block ads, don’t power hardware, and while some cookies expire, they aren’t guaranteed to disappear after a day.
