How does internet work? -IP and DNS In A Nutshell-
Internet. The milestone of our generations. The turning point to the digital revolution. It has transformed everything has touched. How do we interact with our environment, our understanding of the world, the way we communicate with each other, how do we access information, and so on.
All the vast amounts of information to which we have access are stored in data bases. Physical, data bases. This means huge computers processing and storing millions of data. The information travels between these computers to our smart devices through fiber-optic cable.
The information we seek in our devices reach us thanks to our Internt Protocol (IP). The IP of any device it is a unique set of numbers which identify it on the net.
The domains to which we access there are no other thing that a substitution of that numbers for an easy name to remember, thanks to which is easy to gain access to the domain we seek (i.e. 123334554445=YouTube).
The Domain Name System (DNS) plays a fundamental role in this process. It works as a telephonic book, so far as it engages the seek name whit the precise domain number we are looking for. The process is as follows: When we enter a domain into our search engine, this send the data to the DNS in order to identify the searched domain, which connect our IP with the data storage center. The data is transferred in digital format via the fibre cables. These reach our router, which converts this energy into electrical energy and in turn the device converts it into data. When we access the Internet via the wireless network connection, the signal comes to us from an antenna. The antenna distributes the information in the form of magnetic waves to our IP identifier.
