Why this why now
This unit further develops pupils' understanding of network communication by exploring how the internet is network of connected networks. They learn about the protocols that enable devices connected to the internet to communicate with one another and how these protocols are arranged in protocol stacks such as TCP/IP. Pupils will learn how a web browser works and the role of DNS and IP addressing in the WWW. The unit concludes by pupils exploring common threats to networks and the methods that can be used to protect networks.
Prior knowledge requirements
- Pupils recognise how computers can be connected to form networks
- Pupils understand that communicating computers on a network need to follow protocols
- Pupils can describe what services on networks can be made available
