What is a cookie on a computer? It does not refer to the same type of cookie that comes out of the oven. Instead, this type of cookie is created every time you visit a website. While the cookies generated on most websites are perfectly safe, there is a chance that internet cookies could cause a breach in your privacy. In this article, you will learn what a cookie is on a computer, what internet cookies mean, and how to delete cookies.
What Is a Cookie on a Computer?
We will begin by answering the question, “what is a cookie on a computer?” Every time you visit a website, cookies are generated. Cookies are small text files containing data on your internet browsing habits to create a more personalized experience on websites. Cookies allow websites to keep you signed in. It’s why those ads you see seem eerily relevant. Cookies are why your shopping cart stays filled when you accidentally exit the online shop you want to buy from.
There are two types of cookies, first and third-party cookies. First-party cookies are created by the sites you visit while third-party cookies are created by other sites that own content like ads or images on the sites you visit. Both contain information about your preferences.
Cookies identify you to the network server every time you visit a new website by exchanging the cookie between your computer and the network server. The first time you visit a website, a cookie is created and saved. When you visit the website a second time, it will recognize the cookie as you and use the information in the cookie to create a personalized experience.
Internet Cookies Meaning
So what is a cookie on a computer good for? Internet cookies can be useful. They personalize your internet experience to help you find more of the stuff that interests you and less of the stuff that does not. But if you are not vigilant or you are just uncomfortable with your information being stored, cookies can become a problem.
As discussed earlier, there are two types of cookies: first and third-party cookies. First-party cookies are safer than third-party cookies. If you are on a reputable website, you have little to worry about when it comes to first-party cookies. Third-party cookies are a bit trickier. Every ad on a website can generate its own cookie even if you never click on one. The companies attached to these ads, advertising companies, or researchers can gain access to your search history to better understand what you want and target you for ads.
While this is not inherently dangerous, it is understandable that many people would be uncomfortable knowing that their personal information is being obtained and analyzed by companies. Even if the people who have access to the information contained in your cookies have no ill intent, there is always the possibility of a data breach. Your private information could fall into the hands of people with bad intentions.
Viruses and Malware
Other risks related to cookies are viruses and malware. While cookies do not affect how your computer runs, viruses and malware can be disguised as cookies. You must always know what you are installing on your computer. While anti-virus software will recognize and block known attacks, there is always the possibility that it will not recognize the virus or malware. As such, you need to check yourself.
Another cookie issue is the zombie cookie. A zombie cookie can install without your permission and return after you delete it. These cookies are very difficult to remove. It will continue collecting information that can be used by third parties even after you try to delete it. Only visit reputable websites to decrease your chances of dealing with a zombie cookie.
If you find that the risk of cookies outweighs the benefits, consider deleting your cookies and configuring your cookie settings so that no new ones are created. You do not need to always accept cookies. There are both benefits and drawbacks to consider when choosing to accept or not.
