What is a cookie?

A cookie is a simple text file that is stored on a user’s computer (or mobile device) that is created when a user visits a website using a program called a browser (for example Internet Explorer, Firefox or Safari).

A cookie isn't a program itself and doesn't actively do anything on a user's computer. A cookie cannot be used to identify a user personally but they do contribute to improving a user's experience of a website.

A cookie simply allows the website to read the contents of the cookie text file. The text file itself simply contains a unique identifier code; the site name and some digits and numbers.
