A cookie is just a "piece" of information that is saved as text strings on your computer, phone, or tablet. Therefore, your browser keeps cookies when a website asks you to accept them. It may monitor your internet behaviour and you as a result of this. Thus, with the aid of these cookies, the algorithms of the internet work for you to produce material that is personalized for you or preserve login information. Let's take a look at the cookies that Amazon uses to store login information. Your address and contact information are entered on a form when you place an order. Amazon uses this data for the following actions: (A) issues you with an ID, saves your data in its database, and transmits the ID as a cookie to your browser. (b) Your browser's hard drive stores the ID. (c) The ID is sent back to the server when you visit Amazon again. (d) Before delivering you a web page, the server checks your ID and modifies it appropriately.
