Browser cookies are tiny files in a computer designed to hold specific data from websites the user visits. The first time you visit a site, a cookie is downloaded onto your PC. The next time you visit that site, your PC checks to see if it has a cookie from the site, and sends the information contained in that cookie back to the site. The site then ’knows’ that you have been there before, and in some cases, tailors what pops up on screen to take account of that fact. Cookies can be used to remember things like passwords, credit card details, addresses and items in a shopping cart. They inform things like results on google searches and targeted advertising, and can also be used to remember things like passwords, credit card details, addresses and items in a shopping cart. This poses a security risk as this information could obtained by malicious online hackers.
Third-party cookies are browser cookies that are set by a website other than the one you are currently on. For example, an online shopping website like eBay might have a Facebook like button on their site. That like button means that the cookies for that site can be read by Facebook, who could use that information for advertising.
