3.3 The Internet and World Wide Web

In DITA on October 18, 2009 at 10:46 pm

This week in DITA we have been looking at the Internet and World Wide Web. Before this week’s lecture I had always thought that the Internet and the web was the same thing. The confusion seems to come from the fact that we use the terms interchangeably.

The Internet

The Internet essentially is the structure that holds the web. The Internet started life as ARPANET and was first created in 1958 by The Advanced Research Projects Agency (ARPA) to link all the radar systems of the US together. In 1969 the University of California in Los Angeles (UCLA) got hold of ARPANET and since then strides in technology have culminated in the Internet we have today. It is a massive network of networks allowing each connected computer to send information to each other using protocols. Other subnetworks also run on the internet for example email uses SMTP. The diagram below shows others.

The World Wide Web

The World Wide Web was invented in 1989 by physicist Sir Tim Berners Lee. It runs on top of the Internet. The web is made up of large-capacity computers known as web servers which are connected to the Internet through telephone and satellite. Web servers use HTTP protocol to allow computers that are connected to any web server to access files across the web. Files are accessed across the web via web addresses otherwise known as Uniform Resource locator (URL). A URL is made up of the protocol HTTP, the domain name – name of computer hosting the file and the path to the file itself.

In my last post I was introduced to the concept of including Metadata. HTML or Hypertext Markup Language is a form of markup language designed by Tim Berners Lee where HTML tags are used to indicate to the web browser how the web page should be structured.

In this week’s lab we were required to design and link web pages hosted on our City web space.

Here are the web pages I created in this weeks session.
