What is a Cookie?

There has never been so much focus on cookies, and here is not meant grandmother’s homemade cookies with chocolate and nuts. Cookies are quite different when they are mentioned in connection with computers and websites.

But what is a cookie and why all the hype about cookies right now?

What is a cookie?

A cookie is a small text file that is stored on your device (computer, tablet, phone, etc.) when you visit a website. How many cookies a website stores varies from side to side. Some sites do not set cookies, while others set up 50 cookies. Cookies can be stored on a device for a total of seconds to years and are contrary to what many do not think dangerous or harmful.

What do they do?

Cookies can have many different functions, but the most common purposes are:

  • Remember username and password so you don’t have to log in every time you visit a page. For example, Facebook.
  • Remember which items you have placed in the shopping cart on a webshop.
  • Collect statistical information on the use of the website. It may be how long a visitor has been on the page, how many times a visitor has visited the page, whether one has visited since before, and so on.
  • Remember which ads you have seen on the website.

In other words, cookies store information that makes your experience on the website better.
