Τα cookies είναι πολύ μικρά αρχεία κειμένου που τοποθετούνται στον υπολογιστή σας από κάποιον web server (διακομιστή ιστού) που επισκέπτεστε, για να δείτε για παράδειγμα μερικές ιστοσελίδες στο Internet.
Here are a few reasons why not all cookies are served.
They are used for storage data about you and your preferences so that the server doesn't have to repeatedly request that information, potentially slowing down the page load time you're interested in.
Cookies are typically used to store registration data such as name, your address, the contents of a shopping cart, the preferred layout you use on a web page, and so on.
So cookies make it easier for web servers to meet your specific needs and preferences when you visit a page.
Why are they called cookies?
There are different versions. Some people believe that cookies get their name from the "magic cookies" that are part of the UNIX operating system. Still others believe that the name comes from its history Hansel and Gretel, who managed to leave their traces in the woods, scattering the crumbs of biscuits.
Are cookies dangerous?
The most simplified answer is that cookkies, by themselves, are completely harmless. However, some sites and search engines use them to track users as they browse the web, collecting particularly personal information. This information can be conveyed secretly to other websites without permission or a warning to the end user. That's why we often hear cookies in technology news.
Can cookies be used to spy on me?
CooKies are simple text files. They can not run programs or perform some tasks. They can not be used to view the data on your hard drive or to record other information from your computer.
In addition, cookies can only "communicate" with the server that sent them. This makes it impossible for another web server to access cookies set by other servers, and to grab your sensitive personal information.
Why are cookies on the Internet controversial?
Although coo kies can be retrieved only by the server that served them, many online advertising companies serve cookies that contain a unique user ID in ads. Many of the largest advertising companies advertise their products on thousands of different websites. So they can access cookies from all of these sites.
Result; Although the site displaying the ad can not track your web course, the ad serving millions of ads can.
Does it sound a bit like me? But tracking your internet traffic is not necessarily that bad. When tracking is used on a web page, the data collected can help owners modify the page layout, improve popular points, and eliminate or redesign deadlocks for a more effective end-user experience.
For example with one tracking in visits that a website receives, it may appear which point or which page is most interested in the visitors. So the owner can better understand what attracts visitors, which can be used elsewhere on the site.
So tracking data can be used to give site users and site owners more targeted information or make recommendations for purchases, content or services to end users, a feature that many people appreciate.
Do I have to disable cookies on my computer?
It's a question that has different answers depending on how you use the web.
If you visit sites that customize your experience with coo kies, obviously you will not be able to see much if you disable them. Many websites use these simple text files to make your session as personalized and as effective as possible. Just do not have to enter the same information every time you visit.
If you disable cookies in your web browser, the server will not "remember" you and so you will have to constantly give the same information.
Today's browsers can apply a partial pause to the acceptance of cookies, as there are settings that offer a high level of sensitivity. This will give you a warning every time a page "serves" you a cookie. This allows you to accept or reject the "cookies" per location, if you do not break your nerves however.
Before proceeding with a partial ban, think that it will force you to spend more time accepting or rejecting cookies.
Remember: Cookies do not harm your computer or your web browsing experience.
The ones who can do harm are the advertisers and maybe the hackers that can gain access to the sensitive data stored in your cookies.
