What are cookies in computers?
Cookies are text files containing small amounts of information which are downloaded to your device when you visit a website. Cookies are then sent back to the originating website on each subsequent visit, or to another website that recognises that cookie. Cookies are useful because they allow a website to recognise the device you are using and provide you with a better website experience.
Cookies do lots of different jobs, like letting you navigate between pages efficiently, remembering your preferences, and generally improving your user experience. They can also help to ensure that adverts you see online are more relevant to you and your interests. Cookies in themselves do not identify the individual user, just the computer or mobile device you are using via a randomly generated identifying tag.
