What are cookies in the context of web browsing?

• A. Temporary files used for caching
• B. Small pieces of data stored on a user's device
• C. Security features for encrypting data
• D. A type of malware affecting browsers

Answer: (B)

Cookies are small pieces of data stored on a user's device by websites when they are visited. They serve various purposes, primarily to enhance the user experience by remembering information about the user between sessions. For instance, cookies can store user preferences, login information, and shopping cart contents, which allows websites to provide a more personalized experience. When a user revisits a site, the stored cookies can be read to recall previous activities or preferences, making navigation faster and more efficient. This functionality is essential for features such as staying logged in on a site, tracking user behavior for analytics, and facilitating online shopping. Other options such as temporary files for caching, security features for encrypting data, or malware affecting browsers do not accurately describe cookies. While caching is related to storing data temporarily for performance reasons, it is not the same as cookies, which are explicitly intended to maintain information about user sessions. Similarly, security features like encryption are designed to protect data during transmission rather than serving to store user data on devices. Malware, on the other hand, refers to harmful software, which cookies are not; they are benign data stored to improve web functionality.
