Summary of ¿Cómo funciona Internet?

00:00:00 - 00:10:00

This video provides an overview of how the internet works, including how data packages travel from the center of the internet to your mobile phone. It explains how data is transferred using satellites, mobile networks, and wifi networks, and how domain names are used to identify websites. The video also explains how protocols manage the flow of data packets to ensure efficient communication between different applications.

• 00:00:00 The video explains how the internet works, starting with how data is transferred from a distant data center using satellites. If you cannot access the internet using satellites, your device may be connected to the internet through mobile or wifi networks, but eventually it will connect to the cables connecting the data center to your device. Important concepts discussed in the video include an IP address, which is unique to every device connected to the internet, and domain names, which are easier to remember than a long alphanumeric sequence. Servers often store multiple websites on their memory, and can identify a website by its header information instead. In order to access the internet always, we use domain names instead of IP addresses.
• 00:05:00 Internet uses a huge telephone directory known as the "ns" registry to lookup a person's telephone number. If you know the name of a person, but not their telephone number, you can look them up in a telephone directory. Internet's Domain Name Server (DNS) provides the same internet service as your provider of internet services, or other organizations, by administrating the DNS server. This video explains how Internet works as a whole, from the initial request for a domain name to the delivery of the requested website's IP address. A cable connecting the continents with fiber optic cables can be seen in the accompanying images. This cable backbone is responsible for transmitting data through hard-to-reach areas, such as mountainous regions or the ocean, with little loss in quality. The video explains how to use a cellular network to access the internet, and demonstrates how packets of data are transferred over a fiber optic cable. It goes on to explain how protocols manage the flow of data packets, and how this ensures efficient communication between different applications.
