what cookies are and how cookies work

what are cookies?

Cookies are small files which are stored on a user's computer. They are designed to hold a modest amount of data specific to a particular client and website, and can be accessed either by the web server or the client computers.

Good things about Cookies in Computers

Some cookies are more sophisticated. They might record how long you spend on each page on a site, what links you click, even your preferences for page layouts and colour schemes. They can also be used to store data on what is in your ‘shopping cart’, adding items as you click.The possibilities are endless, and generally the role of cookies is beneficial, making your interaction with frequently-visited sites smoother - for no extra effort on your part. Without cookies, online shopping would be much harder.

Bad things about Cookies in Computers

There is nothing especially secret or exceptional about the information gathered by cookies, but you may just dislike the idea of your name being added to marketing lists, or your information being used to target you for special offers. That is your right, just as others are entitled to go along with the process.When cookies first started to appear, there was controversy. Some people regarded them as inherently sneaky - your PC was being used (without warning) to store personal information about you, which could then be used to build a picture of your browsing habits.

Cookies and the Law

Most modern websites use cookies in some way, and it is unlikely that the majority of internet users even notice cookies working away in the background as they browse from site to site. Until now it has been up to individual users to either block or allow cookies using settings in their internet browser. From the end of May 2012 though, a new EU law will require all sites that use cookies to seek your express permission to store and retrieve data about your browsing habits.
