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 how different types of network addressing are combined to enable devices to communicate on a network.
Key Notes
- IP addresses identify devices on a network.
- DHCP assigns IP addresses automatically.
- DNS converts domain names into IP addresses, which identify devices on the internet.
Vocabulary To Learn
- IP address: a unique number assigned to each device on a network, used to identify it and allow it to send or receive data
- domain name server (DNS): a server that works to resolve domain names to corresponding IP addresses
Common Mistakes To Avoid
- All devices on a network use the same IP address, so there's no need for private or public IPs or DNS.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
IP addresses identify devices on a network. DHCP assigns IP addresses automatically.
2. Define this computing term and give one practical example. 'IP address'
a unique number assigned to each device on a network, used to identify it and allow it to send or receive data. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: All devices on a network use the same IP address, so there's no need for private or public IPs or DNS. Correction: Each device needs a unique private IP address on a local network. To access the internet, the router uses a public IP address. DNS translates website names into IP addresses so devices know where to send data.
