DITA session 2

The Internet and the World Wide Web

This session was on how the Internet and the world wide web work and interact with each other.

We talked about how the Internet is a collection of WAN's (wide area networks)

what different DNS (domain name system) mean, ie .com = company .org = organisation ac.uk = academical uk.

How the Internet is a collection of networks and the www is the documents they contain.

how it has become a disruptive technology and changed the way we and industry works for example publishing has moved from paper based to online and the advancement of open source software.

we discussed how a URL (universal resource locater) works from the HTTP (hyper text transfer protocol) through the DNS to the local path and how the hierarchy runs from left to right in the DNS and right to left in the local path.

We then looked at hyper text and HTML and looked at how HTML is written using a variety of tags and how a basic web page can be made using it.

Then we took a brief look at CSS style sheets and how they can add to an HTML web page.

we then in our lab session wrote 2 simple web pages using HTML one linking to the other and hosted them in our student web space.
