In the non-virtual world, a cookie is a kind of food. But, in the digital world, it is a small data which is sent from a website to the user’s digital device. This data is stored in that device and hence, that device remembers that particular data of that visited website. Next time, when that user visits that website using the same device, the web page loads faster. Data like name, contact number, Email id, etc are also stored from a web form. When you will open that form next time, you will find that the form is showing all of those data in the respective boxes and fields.
