One of the primary purposes of cookies is to provide a convenience feature to save you time. The purpose of a cookie is to tell the web server that you have returned to a specific page. For Example, if you personalize GCE pages, or registered with GCE site or services, a cookie helps GCE to recall your specific information on subsequent visits. This simplifies the process of recording your personal information, such as billing address, shipping address, and so on. When you return to the same GCE website, the information you previously provided can be retrieved, so you can easily use the GCE features that you customized.
