Think of all the devices in your house: phones, a laptop, maybe a printer or a smart TV. A home network joins them together so they can talk to each other and share one internet connection.
The router sits at the centre of it all. A good setup makes sharing data easy and fast. Setting it up properly also makes the network faster and safer.
Components of a Home Network
A home network is built from a few parts. Each one has a clear job.
| Component | Its job in the book |
|---|---|
| Router | connects all devices in the network |
| Modem | connects the home network to the internet service provider |
| Network devices | computers, laptops, and mobile phones |
| Network cables | used for wired connections |
| Wi-Fi signals | used by wireless devices to connect |
So the internet comes from your internet service provider. The modem brings it into the house. The router then shares it with every device, by cable or by Wi-Fi.
Wired Network Connections
In a wired network, a cable runs from each device to the router.
The cables used most often are Ethernet cables. They plug straight into a router or a switch. A cable gives high speed and a steady connection. The book also says wired networks are more secure than wireless ones. The downside is simple: a device on a cable cannot move around freely.
Wireless Network Connections
In a wireless network, there are no cables at all.
Wi-Fi is the wireless technology most homes use. You can walk around with your phone and stay connected, as long as you are within range. Wireless networks are easy to set up and use. In some cases, though, they can be slower than a wired network.
| Wired | Wireless | |
|---|---|---|
| How it connects | cables (Ethernet) | radio signals (Wi-Fi) |
| Speed | high speed, stable | may be slower in some cases |
| Security | more secure | less secure than wired |
| Moving around | devices cannot move freely | devices can move freely within range |

Short questions
1.What is a home network?2 marks
Answer
From the book: "A home network is used to connect different devices in a house. It helps computers, mobile phones, and printers to communicate with each other. All devices can share the same internet connection."
2.Name the components of a home network.3 marks
Answer
From the book: "A router connects all devices in the network. A modem connects the home network to the internet service provider. Computers, laptops, and mobile phones are network devices. Network cables are used for wired connections. Wireless devices use Wi-Fi signals to connect."
3.What is the role of a router and a modem in a home network?2 marks
Answer
From the book: "A router is the main device in a home network." "A router connects all devices in the network. A modem connects the home network to the internet service provider."
4.What is a wired network? Write its advantages.3 marks
Answer
From the book: "A wired network uses cables to connect devices. Ethernet cables are commonly used in wired networks." Advantages: "Wired connections provide high speed and stable performance. These networks are more secure than wireless networks."
5.What is a wireless network?2 marks
Answer
From the book: "A wireless network connects devices without using cables. It uses radio signals to send and receive data. Wi-Fi is the most common wireless technology used in homes."
6.Write two differences between wired and wireless network connections.4 marks
Answer
From the book: a wired network "uses cables to connect devices", while a wireless network "connects devices without using cables" and "uses radio signals". In a wired network "devices cannot move freely because of cables"; in a wireless network "Devices can move freely within the network range." Wired networks "are more secure than wireless networks", and wireless networks "may be slower than wired networks in some cases."
Long questions
1.What is a home network? Describe the components of a home network.6 marks
Answer
Cover the topic opening and "Components of a Home Network", using the book's text:
- Home network (verbatim): "A home network is used to connect different devices in a house. It helps computers, mobile phones, and printers to communicate with each other. All devices can share the same internet connection."
- Main device and setup: "A router is the main device in a home network. Network setup makes data sharing easy and fast. Proper configuration improves network speed and safety."
- Components (verbatim): "A router connects all devices in the network. A modem connects the home network to the internet service provider. Computers, laptops, and mobile phones are network devices. Network cables are used for wired connections. Wireless devices use Wi-Fi signals to connect."
- A labelled sketch (internet service provider, modem, router, wired devices with network cables, wireless devices with Wi-Fi) helps the answer.
Aim for 150-250 words.
2.Explain wired and wireless network connections. Compare them.8 marks
Answer
Cover "Wired Network Connections" and "Wireless Network Connections", using the book's text:
- Wired (verbatim): "A wired network uses cables to connect devices. Ethernet cables are commonly used in wired networks. Devices are connected directly to a router or switch. Wired connections provide high speed and stable performance. These networks are more secure than wireless networks. However, devices cannot move freely because of cables."
- Wireless (verbatim): "A wireless network connects devices without using cables. It uses radio signals to send and receive data. Wi-Fi is the most common wireless technology used in homes. Devices can move freely within the network range. Wireless networks are easy to install and use. They may be slower than wired networks in some cases."
- Comparison table: cables (Ethernet) vs radio signals (Wi-Fi); high speed and stable vs may be slower in some cases; more secure vs less secure; devices cannot move freely vs move freely within the network range; connected directly to a router or switch vs easy to install and use.
Aim for 200-300 words.
