What is Cookies?


All About Cookies
Cookies are usually small text files that are stored on your computer's browser directory or program data subfolders. Cookies are created when you use your browser to visit a website that uses cookies to keep track of your movements within the site, help you resume where you left off, remember your registered login, theme selection, preferences, and other customization functions.
Cookies are often indispensable for websites that have huge databases, need logins, have customizable themes, other advanced features.
Cookies usually don't contain much information except for the url of the website that created the cookie, the duration of the cookie's abilities and effects, and a random number. Due to the little amount of information a cookie contains, it usually cannot be used to reveal your identity or personally identifying information.
There are two types of cookies: session cookies and persistent cookies. Session cookies are created temporarily in your browser's subfolder while you are visiting a website. Once you leave the site, the session cookie is deleted. On the other hand, persistent cookie files remain in your browser's subfolder and are activated again once you visit the website that created that particular cookie. A persistent cookie remains in the browser's subfolder for the duration period set within the cookie's file.
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
