Cookies are small pieces of data stored on a user's device by a website while the user is browsing. They serve various purposes such as remembering user preferences, enhancing user experience, and tracking user behavior.

Cookies are commonly used by websites for tasks like:

1. Session Management: Cookies can store session information, allowing websites to recognize users and maintain login sessions.
2. Personalization: Websites can use cookies to remember user preferences, such as language settings or customized layouts.
3. Tracking: Cookies enable websites to track user behavior, such as pages visited, links clicked, and time spent on each page. This data can be used for analytics and targeted advertising.
4. Authentication: Cookies are often used to authenticate users, ensuring that only authorized users can access certain parts of a website.
5. Advertising: Cookies are utilized for targeted advertising, allowing websites to deliver ads that are relevant to a user's interests and browsing history.

It's important to note that while cookies can enhance user experience and provide valuable functionality to websites, they also raise privacy concerns. Users may have concerns about their online activities being tracked, leading to regulations like the GDPR (General Data Protection Regulation) in Europe, which requires websites to obtain user consent before storing cookies and to provide mechanisms for users to manage their cookie preferences.
