Cookies are small pieces of data stored on a user’s device by web browsers while browsing websites. They serve various purposes, including remembering user preferences, tracking user sessions, and delivering targeted advertising. Cookies enable website owners to enhance user experience by retaining login information, language settings, and shopping cart contents. However, they also raise privacy concerns as they can track user behaviors across different sites. Consequently, many browsers now provide users with options to manage and delete cookies, promoting transparency and user control.
