Security and privacy

Depending on what website I am on will determine what information i supply, is it is a secure website and they ask for information such as address, phone number etc then i provide it.A cookie is a message given to a Web browser by a Web server. The browser stores the message in a text file. The message is then sent back to the server each time the browser requests a page from the server. You should never leave your computer unattended because you don't know who will be walking by and have access to information such as bank details, address etc.
