What are cookies?
Cookies are small text files sent to your computer or mobile phone that help your browser navigate through a particular website. The cookie file is generated by the site you're browsing and is accepted and processed by your computer's browser software. The cookie file is stored in your browser's folder or sub-folder.
Your browser accesses the cookie file again when you return to the website that created the cookie file. The browser uses the information stored in the cookie file to help ease your navigation of the website by letting you log in automatically or by remembering settings you selected during your earlier visits to the website, among many other functions. Cookies are not programs and do not collect information from your device or pass on computer viruses. A cookie does not hold any information about which sites you visited before this one.
Why are cookies used?
Cookies make the interaction between users and web sites faster and easier. Without cookies, it would be difficult for a web site to remember the user's preferences or registration details for future visits.
They allow websites to create a customised view of pages to which you navigate. For example, they are commonly used to authenticate or identify registered users of a website without requiring them to sign in each time they access it. Other uses include maintaining a ‘shopping basket’ of goods a user has chosen to purchase, site personalisation (presenting different pages to different users) and tracking the pages a user has visited on a site for analysis purposes. Cookies may come with or without an expiry date.
Cookies without an expiry date exist until the browser is closed, while cookies with an expiry date may be stored by the device until the expiry date passes.
