Pieces of information transferred to your computer’s hard disk from a website are known as “cookies”.
They are not computer programs, just small information files which allow websites to store and access information about a user’s browsing patterns.
There are different types of cookies: temporary cookies (or session cookies) are erased when the browser closes; persistent cookies are not erased but stay until they are actively erased or they expire (which is dependent on how long the website has programmed the cookie to last).
Most browsers are automatically set to accept cookies.
You may disable cookies on your browser, but remember that if you do, you may lose many features which are needed to enable the website to work properly.
