The Web

Let us first have a look at this medium, that we seem to know so well. It was  1991 when the World Wide Web became active as a platform for anyone to participate in. It had its origins in military data accessing systems.

Web Services

For the Web to functions it requires a number of Web Technologies. In order to understand what Web Technologies are used for it is important to have a common understanding of web publishing languages such as HTML, CSS, JavaScript or XML.

To view any website on the Internet most people use a web browser. Web browsers work by connecting over the Internet via modem or ISDN (Integrated Services Digital Network) via a server or ISP (Internet Service Provider) to remote machines, asking for a particular document (or page) and then formatting the documents they receive for viewing on a computer.

To allow you to view a web page on your computer, web browsers use a special language called HTTP (HyperText Transfer Protocol). The remote machines containing the documents run HTTP servers. A HTTP server receives a request for a page, and sends it to the computer. The page can then be viewed through the browser.

Each document that is stored on the Web has a particular URL (Uniform Resource Locator). This tells the browser which server to go to to get the document. The syntax of the URL is simple to understand.

The standard for web documents is HTML. HTML is a Mark-up language that uses tags to create all the Web pages. HTML can be used to create formatted text that allows web browsers to make web pages viewable on their screens.

HTTP can also include images, sound, animation and video clips. HTTP weaves together all the relevant elements of the page and describes how it should be represented on your browser. It can also link to other pages or sites on the Web through hyperlinks.

What is the Internet?

So, what is the Internet? I would like to post this as a question to the class.

Let us share our views of what the Internet actually is. What do we see in it, what it is it made up of? What does it symbolise or represent to you?

Please participate in the class discussion before reading on. If you have missed the class and are following the notes online please stop for a moment and think about the question above. You may want to write your responses down before you continue!

Andrew Blum, a journalist and author of the book ‘Tubes’ explored what the Internet actually is in a physical form. Please use your head phones and view this video from his TED talk in September 2012: Andrew Blum: Inside the physical.

So, has your answer to what the Internet is changed?
