A cookie is a small amount of data, which often includes an anonymous unique identifier, that is sent to your browser from a web site's computers and stored on your computer's hard drive.

Each web site can send its own cookie to your browser if your browser's preferences allow it, but (to protect your privacy) your browser only permits a web site to access the cookies it has already sent to you, not the cookies sent to you by other sites.

Choices about Cookies
You can configure your browser to accept all cookies, reject all cookies, or notify you when a cookie is set. (Each browser is different, so check the "Help" menu of your browser to learn how to change your cookie preferences.)
If you reject all cookies, you will not be able to use services/offerings that require you to "sign in," and you may not be able to take full advantage of all offerings. However, many Gates services/offerings do not require that you accept cookies.
