In web browsing, what does session storage refer to?

• A. Session storage data persists across all browser sessions.
• B. Data stored on the server.
• C. Data used to store credentials in cookies.
• D. In web browsing, the information that is stored and can be reused from a single web session.

Answer: (D)

Session storage is a client-side storage mechanism that keeps data for the duration of a single browser tab session. It lets you store key-value pairs in the browser and reuse them while the tab is open, even if you reload the page. The data is specific to that tab and origin, and it’s cleared once the tab or window is closed. This is different from persistent storage like localStorage (which survives browser restarts) and from server storage or cookies (which involve sending data to a server). So the best description is that it stores information that can be reused during a single web session.
