Which term describes a file that tracks user activity on a website?

• A. Cache
• B. Cookie
• C. Script
• D. Cache Memory

Answer: (B)

The term that describes a file that tracks user activity on a website is a cookie. Cookies are small pieces of data stored by a web browser while browsing a website. They are used to remember information about the user's visit, such as login credentials, preferences, and tracking data for analytics. This allows websites to provide a more personalized experience upon subsequent visits, as the stored data can help remember user settings and behavior.

While cache and cache memory relate to storing data for faster access, they do not specifically track user activity like cookies do. Scripts are sets of instructions that can run on a website to perform actions, but they do not inherently track user behavior in the same way cookies do. Therefore, cookies are the appropriate choice for describing files that keep track of user activity on a website.
