why internet and web aren't the same thing

The Internet and the World Wide Web are often mistaken to be the same thing. When really The World Wide Web is just a portion of the Internet using one of many protocols.

Internet: The Internet is a massive publically availible global network of devices interconnected to each other via protocols.

Many different protocols are used to transfer data between devices connected to the Internet.

Ill try to explain a few of the key protocols used for browsing the web using the least amount of networking lingo I can:

Internet Protocol: Every devices connected to the internet has a unique I.P (Internet Protocol) address to determine the location of the device on the network. For example even the server that hosts www.teamtreehouse.com has an I.P address (173.247.98.20). (Try it now yourself put 173.247.98.20 into your web browser address bar and you should be directed to teamtreehouse)

DNS Protocol: When you go to a website for example teamtreehouse.com your browser uses DNS (Domain Name System) protocol to connect to a DNS server to translate the simplified web address into it's original I.P address.

HTTP: HTTP (Hypertext Transfer Protocol) is the protocol that the WWW (World Wide Web, The Web) uses to transfer HyperText data across networks such as the Internet, Local Intranet and partially public Extranets. When you go to a website for example www.teamtreehouse.com, first your browser requests the I.P address for www.teamtreehouse.com from a DNS server, once your browser has the I.P address of the server it sends a HTTP request to the server, without going into too complicated networking, basically the server returns an HTTP header response with information about what is contained at the address, your browser and the server will bounce back and fourth with HTTP requests until the data matches the HTTP header sent from the server (it's a bit more complicated than this and involves more protocols from your router to the server to determine that the data recieved is correct and not corrupt but this is the basic idea of how it works)

World Wide Web: The World Wide Web (WWW) basically refers to the global web of hypertext files connected to eachother via hyperlinks using the HTTP Protocol on the Internet Network.
