A very comprehensive article explaining how computers communicate, what the internet is and what services run on it. On the third page (labelled page 34) there is a very good unplugged classroom activity that can be used to model how packets of data are passed by the internet. The document also contains classroom activities that explore (amongst others) the following:
- A role play relating to emails and their security
- Uniform Resource Locators (URLs) are the precise location on the Web where web pages or their components are stored
- World Wide Web (WWW) usage across a week for different family members
- HyperText Mark-up Language (HTML) – which is the computer language in which the content and structure of web pages are described
- Search engines and how to filter searches
