Some of the reasons web sites use cookies are

described below

 Customization

Some sites use cookies to record your surfing
patterns, and then optimize the information the

site subsequently presents. For example, a

search site may present you with advertising

that reflects your interests based on the

keywords you search for.

 Distribution

One of the key reasons web sites use cookies is to distribute the

information storage. A cookie takes up a small amount of space on an

individual computer, but would take up a very large amount of space if

they all had to be stored back on a web site's server.

 Security

If a cookie was stored on a web site, then it can be accessed by anyone

with access to that web site. However, when the cookie is stored on your

computer, then it can't be accessed by hackers that break into the web

site.
