Cookies are small text files stored on a user’s computer or mobile device by a web server. They are used to remember information about the user and their preferences, such as login information, shopping cart contents, and browsing history. They are also used to track user behavior and collect data for analytics and advertising.
When a user visits a website, the website sends a cookie to the user’s computer or mobile device. The browser then stores the cookie and sends it back to the server with each subsequent request to the same website. This allows the website to remember the user’s preferences and to provide a more personalized experience.
Two types of cookies:
Session cookies: These cookies are temporarily stored in the user’s browser and are deleted when the user closes the browser. They are used to remember information about the user’s session, such as login information.
Persistent cookies: These cookies are stored on the user’s computer or mobile device for longer and are not deleted when the user closes the browser. They are used to remember user preferences, such as login information, and to track user behavior over time.
Cookies are widely used by websites and web applications to provide a more personalized user experience and to track user behavior. However, they can also be used to collect personal data and track users’ browsing habits, which can be a privacy concern.
