A cookie is information (a small text file) that a site saves to your computer using your web browser. Cookies enable personalization of your web experiences. For example, a cookie may allow sites to record your browsing activities – like what pages and content you’ve looked at, when you visited, and whether you clicked on an ad. Cookies can help sites remember items in your shopping cart, your log-in name, or your high game scores. Cookies are typically exceedingly small (less than the size of a file containing a sentence or two) and take virtually no space on or slow down your computer.
