Cookies are small pieces of data that are stored on a user’s device when they visit a website. They are often used to track a user’s browsing activity and remember their preferences and login information. Cookies are usually sent back and forth between a website and a user’s device each time the user visits the website.
How do Cookies Work?
When a user visits a website, the website may send a cookie to the user’s device. The user’s device then stores the cookie, and sends it back to the website each time the user returns. This allows the website to recognise the user and personalise their experience.
For example, if a user visits an online store and adds items to their cart, the website may use a cookie to remember the items in the user’s cart so that they can continue shopping later.
