Unit Summary
In this unit pupils will explore the impact networks have on our daily lives. They will define what a network is and explore the benefits of networking, before covering how data is transmitted across networks using protocols. They will investigate different types of network and hardware required.
Lesson Summary
You will learn to explain how devices on a computer network use protocols to communicate.
Key Notes
- Protocols are sets of rules that are followed to allow communication to take place.
- IP adresses are given to devices on a local network.
- IP addresses need to be unique on the same network.
- The IP addresses of both the receiver and sender need be added to every network message.
Vocabulary To Learn
- network: a group of devices connected together, wirelessly or using cables, to enable communication
- protocol: a set of rules used to allow devices to communicate with each other
- IP address: a unique number assigned to each device on a network, used to identify it and allow it to send or receive data
Common Mistakes To Avoid
- Computers only need protocols when sending emails or accessing websites.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Protocols are sets of rules that are followed to allow communication to take place. IP adresses are given to devices on a local network.
2. Define this computing term and give one practical example. 'network'
a group of devices connected together, wirelessly or using cables, to enable communication. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Computers only need protocols when sending emails or accessing websites. Correction: Protocols are essential for all sorts of activities, not just email or browsing websites. Protocols are also needed for streaming movies, playing online games, making video calls, etc. Anything being sent across a network needs to follow a protocol.
