1. Understanding the internet

2. In this session we will look at
what makes up a web address (URL)
what we can ignore in a web address
to help our internet research
domain names & domain extensions
some country extensions to domain
names

3. By the end of the lesson you will be able to:
Explain what a URL is
Match domain extensions to their
descriptions
Recognise the domain extensions of other countries
Differentiate between the different websites
of one company

4. Uniform Resource Locator
URL stands for:
Uniform Resource Locator

5. http://www. World Wide Web Hyper Text Transfer Protocol
Most websites begin this way so you can ignore this part of the URL when looking for appropriate websites for your research.

6. The domain name comes after http://www.
e.g.
would take you to the home page of a company called the BBC

7. The rest of the URL just describes the pathway separated by / e.g.
So we can see that not only is the link from the home page of bbc:
it is then taken from the arts page
and it is then taken from a sub-section
called multimedia
and it is then taken from a page about
turner

8. Sometimes the URL will end with html.
html stands for:
hypertext markup language
It is the computer language or code most internet pages are programmed in

9. bbc = descriptive part of name co.uk = domain extension
domain names
e.g.
bbc = descriptive part of name
co.uk = domain extension

10. Country domain extensions

11. Other domain extensions
