Which of the following accurately defines a cookie?

A cookie is accurately defined as a small text file that includes information specific to the user's interaction with a specific website. This definition captures the primary purpose and functionality of cookies in web browsing. Cookies are used to remember a user's preferences, login information, and other data related to their browsing session, enhancing the user experience by allowing websites to recognize returning users and maintain session information.

The significance of cookies arises from their ability to store data directly in the user's device, making it easier for websites to retrieve this information when the user returns. This process is essential for tracking user behavior, personalizing content, and improving website functionality.

In contrast, other options present inaccuracies regarding the nature of cookies. For example, the first option suggests that cookies are binary files identifying users and their last visit, but cookies are actually stored in plain text format, often including key-value pairs rather than simply identifying a user. The second option mischaracterizes cookies as hyperlinks, which does not reflect their function. Finally, the fourth option describes cookies as executable files, which they are not. Cookies cannot launch other applications or files; they merely provide data to websites for better interactivity.
