What are Cookies and why are they used?

A cookie is a small text file that is stored on your computer or other internet-connected device in order to identify your browser, provide analytics, remember information about you such as your language preference or login information. They're completely safe and can't be used to run programs or deliver viruses to your device.

Cookies are designed to hold a modest amount of data specific to a particular client and website and can be accessed either by the web server or the client computer. This allows the server to deliver a page tailored to a particular user, or the page itself can contain some script that is aware of the data in the cookie and so is able to carry information from one visit to the website (or related site) to the next.

Why are Cookies Used?

Cookies are a convenient way to carry information from one session on a website to another, or between sessions on related websites, without having to burden a server machine with massive amounts of data storage. Storing the data on the server without using cookies would also be problematic because it would be difficult to retrieve a particular user's information without requiring a login on each visit to the website.

If there is a large amount of information to store, then a cookie can simply be used as a means to identify a given user so that further related information can be looked up on a server-side database. For example the first time a user visits a site they may choose a username which is stored in the cookie, and then provide data such as password, name, address, preferred font size, page layout, etc. - this information would all be stored on the database using the username as a key. Subsequently when the site is revisited the server will read the cookie to find the username, and then retrieve all the user's information from the database without it having to be re-entered.

How to block cookies?

If you don't want sites to store cookies on your computer, you can block them. But blocking cookies is not recommended because it might prevent some pages from displaying correctly, or you might get a message from a site letting you know that you need to allow cookies to view that site. You can block cookies by simply going to your browser's settings and then turning off the cookies.
