Unit Summary
In this unit pupils will be develop their understanding of computer networks by looking at network models and the tasks performed by network hardware. They will discover the differences between wired and wireless transmission media and the factors that can affect the performance of a network.
Lesson Summary
You will learn to explain the factors affecting network performance.
Key Notes
- Factors such as bandwidth, range, latency and the number of devices connected affect network performance.
- Transmission time depends on file size and data transfer rate.
- Routing manages network traffic efficiently.
Vocabulary To Learn
- bandwidth: the maximum amount of data that can be transferred over a communication channel
- routing: the process where routers select the best path for data to travel across a network, using rules called routing protocols
Common Mistakes To Avoid
- The only factor that affects network performance is how fast your internet connection is.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Factors such as bandwidth, range, latency and the number of devices connected affect network performance. Transmission time depends on file size and data transfer rate.
2. Define this computing term and give one practical example. 'bandwidth'
the maximum amount of data that can be transferred over a communication channel. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: The only factor that affects network performance is how fast your internet connection is. Correction: Connection speed does affect performance, but it is also influenced by factors like bandwidth, latency, number of users, packet loss, hardware quality and interference on wireless networks.
