Unit Summary
In this unit pupils will recognise the internet as a network of networks. They will learn that the World Wide Web is part of the internet. They will evaluate online content to decide how honest, accurate, or reliable it is, and understand the consequences of false information.
Lesson Summary
You will learn to explain how networks are connected together and why it is important they are protected.
Key Notes
- Networks can be physically connected to other networks.
- Data can be shared between computers on different networks.
- Networks need protecting to keep the information on them secure.
- The internet is a network of networks.
Vocabulary To Learn
- router: a device that manages the flow of data between computer networks
- network: a group of interconnected computing devices
- internet: the global system of interconnected computer networks
Common Mistakes To Avoid
- Because a computer is connected to a network, it will be connected to the internet.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Networks can be physically connected to other networks. Data can be shared between computers on different networks.
2. Define this computing term and give one practical example. 'router'
a device that manages the flow of data between computer networks. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Because a computer is connected to a network, it will be connected to the internet. Correction: Not necessarily, it still needs a connection to the internet through a router. Networks can be created and used for many different purposes and that does not always have to involve being connected to the internet.
