Guiding Question 3 What is the Internet, where is it, and how does it work? For this week, Team 8 concentrated on bringing you information about the internet. Whether it be basic understanding of components of the internet, how all the devices work together to bring the internet to life or using social media to keep in contact with the rest of the world. For the first time ever, the world is truly at your fingertips. Communication with people around the world is now possible through the world of the internet. Powerful resources can be tapped into, anywhere on the planet.
How does the Internet work? That is a great question! The Internet has grown in an explosive way and it seems difficult to escape the barrage of .coms seen increasingly on television, seen in magazines and heard on radio. The Internet has become such a large portion of our everyday lives, a good understanding is needed to use this new tool most efficiently.

Just HOW do these networks “talk” to one another?
The BIG secret of the “Net” is a network protocol called TCP/IP. This is a special kind of coding system that lets computers electronically describe and interpret (send and receive) data over the network. The term actually refers to two separate parts: the transmission control protocol (TCP) and the Internet protocol (IP). Joined together they form the unique “language” of the Internet. Every computer that hooks to the Internet understands these two protocols and uses them to send and receive data from one computer to the next computer along the network highway. TCP breaks down every piece of data such as an email message or a web page into small chunks called packets. The IP protocol then figures out how the data is supposed to get from point A to point B by passing through a series of routers. If your web page was broken into ten packets, then each of those will have traveled a completely separate route. But you’ll never know it, because as the packets arrive, TCP takes over again, recognizing each packet and checking to see if it’s complete. Once it has acknowledged all the packets, TCP reunites them into the original form.
The World Wide Web
Although the terms Web and Internet are often used synonymously, they’re actually NOT the same thing. The World Wide Web you know the “www” that starts most of the websites we use, is a subdivision of the Internet a collection of interweaved documents that work together using a specific Internet protocol called HTTP(Hypertext Transfer Protocol). HTTP is just one of many protocols that are used on the internet. Others include Simple Mail Transfer Protocol (SMTP),File Transfer Protocol (FTP) .The essential feature of the Web is its ability to connect pages to one another also to audio, video, and image files with something called hyperlinks. The Web is based on a set of rules for exchanging text, images, sound, video, and other multimedia files, which is collectively known as HTTP, or Hypertext Transfer Protocol .Web pages can be sent over the Net because browsers and Web servers both understand HTTP. Web pages are written in HTML, or Hypertext Markup Language, which tells the Web browser how to display the page completely .
