Unit Summary
In this unit pupils will explore digital devices, with an initial focus on inputs, processes, and outputs. Pupils will be introduced to computer networks, including devices that make up a network infrastructure and the benefits of connecting devices in a network.
Lesson Summary
You will learn to explain how digital devices can be connected.
Key Notes
- Computer networks are made up of a number of parts.
- Data can be passed between devices.
- Networks have switches, servers and wireless access points.
Vocabulary To Learn
- server: a networked computer that manages, stores and provides data such as files to other computers
- wireless access point: a network device that allows wireless computing devices to connect to a wired network
- network: a group of interconnected computing devices
Common Mistakes To Avoid
- Data travels in one large piece across the network.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Computer networks are made up of a number of parts. Data can be passed between devices.
2. Define this computing term and give one practical example. 'server'
a networked computer that manages, stores and provides data such as files to other computers. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Data travels in one large piece across the network. Correction: Data is split into smaller packets, which travel separately and are reassembled at the destination.
