Internet has been a technology that undeniably has revolutionized everything around us. The way in which we relate to each other, how do we understand our environment, how do we conceive our educational systems, they way we reach the information, how do we apply for jobs, so on and so forth.

All the information that we have access through this technology is stored in data bases. Physical data bases. Which means physical computers entitled of data storing. The transmission of the stored information in these computers to our devices mainly is produced through fiber-optic cables.

The information we order on internet is reached to our devices thanks to our IP identification. This IP identification is a unique identification of each device which allows to target particularly each device connected to internet.

The internet domains there are not other things than a substitute of the IP direction of the server to which we want to access, making easy its localization (for example, Google = 1100995847874).

The function of the DNS is to act as a “phone book” that identifies the name with the number. So, when we enter a domain in the browser, it sends it to the DNS service which identifies the IP address, which is the function of the DNS is to act as a “phone book” that identifies the name with the number. So, when we enter a domain name in the browser, it sends it to the DNS service, which will match the IP address, which directs us to the database where the information we request is stored.  The data is transferred in digital format via the fiber 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 through the wireless network connection, the signal comes to us from an antenna.  Being the antenna the one that distributes to our IP identifier the information in form of magnetic waves. It directs us to the database where the information we request is stored.  The data is transferred in digital format via the fiber cables.
