In search for information, people once used to go to libraries. Fortunately, there were librarians helping you to find the information you were looking for. Although libraries are not (yet) extinct, the internet is trying to take over.
The world’s biggest online search engine data centers are enormous. Continuously they process all information to make sure you can access it anytime, anywhere. They are the brains of Mr. Google, the librarian that finds your information in less than a second.
