How Internet works

• What is Internet?

          Internet is a network that is in thousands of computers around the world. This is connected by wides, conecctions, routers and more things.

• How it works

      When you connect to internet a IP address appear (The IP address is like a ''registration'', but when you dissconect internet, the IP dissapears, the router provides us the IP address and it's a physical way to connect us to internet .But there's another registration called MAC that is like the same but it doesn't dissapear when yoyu disconnetc internet, normally is physical). Then, when we want to display a website, sometimes the page is writte  in a lenguage called HTML, that is a language used to write in the blogs and the most of the webpages on internet, and it's hosted  on a computer called server (A server is a computer program that can manage  the access to a service in a network). When we open our browser (the program that connects us to the server in all the world  and provides us to connect to another pages) and write the URL ( an address that indentifies a website, this is one example:https://www.google.es/ ) the router connects your computer to a DNS server ( is a server that check the database for our IP address to connect to the URL that we write it before and then the DNS send us the information packets to the address. Now, a request is sent to the server to have this webpage on our screen. To understand the computer and the server beetween them, their use the protocol (Set of rules that the computers use to comunicate with another computer) of the most common like the HTTP and the IP/TCP protocol. The server,very fast, create a path beetween routers to send us the information. Finnally our computer recives the document.
