A cookie is a “text-only” string of information that a website transfers to the cookie file of the browser on your computer’s hard disk so that the website can remember who you are.
A cookie will typically contain the name of the domain from which the cookie has come, the “lifetime” of the cookie, and a value, usually a randomly generated unique number. Two types of cookies are used on this website-session cookies, which are temporary cookies that remain in the cookie file of your browser until you leave the site, and persistent cookies, which remain in the cookie file of your browser for much longer (though how long will depend on the lifetime of the specific cookie).
Cookies can help a website to arrange content to match your preferred interests more quickly. Most major websites use cookies. Cookies cannot be used by themselves to identify you.
