Why are computer cookies sometimes good and sometimes bad?

So far, the answer does not solve the main reason browser allows cookies. This makes them incomplete

Authentication cookies are the most common way for a web server to check if a user is logged in and the account the user is logged in to. Without such a mechanism, the website does not know whether to send a page containing confidential information - HTTP cookie - Wikipedia

That is, cookies are essential for most websites that allow logins. If you disable cookies, you will not be able to use these sites.

However, cookies are also used to track, save and transfer your activities on the website. Cookies are not the only way to do this.

To log in and use most web features, you need to use cookies. Cookies can be used to track your activity. Simply disabling cookies does not necessarily prevent you from tracking or losing personal data.

Cookies are not spyware but really small programs (text files). It is usually secretly placed by a Web site (Web server) on the computer to gather specific information such as web habits. These are very small files (usually only a few bytes) and occupy little disk space.

If you place them on your computer without your permission, cookies can be terrible and they can be used to steal important personal information such as passwords, bank accounts, credit card numbers, social security numbers, etc. It is put there.

But sometimes cookies are good as they look magical. For example, when a person visits YouTube, the name of the user is greeted, and the user is informed of what other dance video they want to see. If a user has seen a dance related video on YouTube in the past

Also, if you have cleaned up cookies on your computer and have not installed hundreds of cookies for a long time, they may occupy some disk space.

Cookie is just small data and is somewhat similar to "public". In other words, the site may remain on the user's computer. The next time you visit the site, the browser alerts you that the site left a note by sending a copy to that site.

Cookies are very useful, as explained in other answers - how you logged in before, how you are, and how you can remember where you left when you last visited To the server.

Cookies may have a bad purpose. The main problem with cookies is that cookies can be used to keep track of how you are using the internet.

At the time of writing this article, there are few Twitter and Facebook icons at the bottom of the input box. These are all cookies that are loaded from these servers and leave these sites on my computer. Therefore, Twitter and Facebook will recognize that I accessed this page.

Sometimes you will find a loop at the bottom of the abyss. If I eat cookies, I'll feel better soon, so you will eat cookies (so that as long as conclusion changes, so much cookies will not make you feel sick) . These loops are easy to drop when we like the conclusion we draw or when there is no reason to accept other conclusions. Therefore, we decide our actions. . Factors can change this so that different locations can be identified to use the same place as before to derive new conclusions.

At the moment, it is difficult to prove that a bad decision is correct. It is easy for us to break personal commitments. Sometimes we can not control our anger, we cry to our children. Sometimes cookies look very nice, we can not refuse. I like to work hard in order to achieve the goal. Sometimes I think I would rather go to sleep than go to the gym. If we keep it for so long, our whole life - our past - will not be what we expected. Peter Pan writer J M Barrie says: "Everyone's life is a diary - in this diary he means writing a story and writing a different story - his volumes are compared, I promise to succeed."

LW: This is absolutely difficult, you have good and bad days. When I want to buy biscuits, I will exaggerate and buy two bananas. I get cookies, but I also get bananas so at least they will know that I do not only eat cookies. People always think I eat only cookies. It is often said that I sit on a cheeseburger mountain all day. This will come to your mind. I am an ordinary person and I have to prove to people that he is eating all kinds of food. Sometimes I am weak, I do not have it
