What are Cookies?

Internet Cookies are the small files that store data and information related to the websites you’ve visited. It may include your browser info, passwords, visited pages, preferences, IP address, time and date of visits, etc. Whenever you visit a website, the browser sends the already loaded cookies to the server that makes the pages load fast and serve ads, and other content according to your previous visits.

The lifespan of the cookies is usually limited and it is decided by the creators of different websites. Sometimes the web browsers you use decide the lifespan of cookies.

Cookies usually contain all information about the user that is collected while visiting a website, or a web app. Netscape introduced the cookies first and then, everyone followed it. We generally see a Cookies consent bar or popup whenever we visit a website for the first time.
