What is a cookie?
A cookie is a harmless text file that is stored in your browser when you visit almost any web page. The usefulness of the cookie is that the website is able to remember your visit when you navigate that page again. Although many people do not know, cookies have been used for 20 years, when the first browsers for the World Wide Web appeared.
What is NOT a cookie?
It is not a virus, nor a Trojan, nor a worm, nor spam, nor spyware, nor does it open pop-up windows.
What information does a cookie store?
Cookies do not usually store sensitive information about you, such as credit cards or bank details, photographs, your ID or personal information, etc. The data they save is of a technical nature, personal preferences, personalization of contents, etc.
The web server does not associate you as a person but your web browser. In fact, if you regularly browse Internet Explorer and try to navigate the same website with Firefox or Chrome, you will see that the website does not realize that you are the same person because it is actually associating the browser, not the person.
What kind of cookies exist?
Technical cookies: They are the most elementary and allow, among other things, to know when a human or an automated application is browsing, when an anonymous and registered user navigates, basic tasks for the operation of any dynamic website.
Analysis cookies: They collect information about the type of navigation you are doing, the sections you use most, products consulted, time zone of use, language, etc.
Advertising cookies: They show advertising based on your browsing, your country of origin, language, etc.
What are own and third-party cookies?
Own cookies are those generated by the page you are visiting and those of third parties are those generated by external services or providers such as Facebook, Twitter, Google, etc.

So that you understand the scope that cookies may have to deactivate, I show you some examples:

Online stores: You will not be able to make online purchases, they will have to be telephone or visiting the physical store if you have it.
It will not be possible to customize your geographical preferences such as time zone, currency or language.
The website will not be able to perform web analytics on visitors and web traffic, which will make it difficult for the website to be competitive.
You will not be able to write on the blog, you will not be able to upload photos, post comments, rate or rate content. Nor can the web know if you are a human or an automated application that publishes spam.
It will not be possible to display sectorized advertising, which will reduce the advertising revenue of the web.
