Step 1
Identify if the house network is a LAN or a WAN.
Answer
Network type: LAN.
Justification: A local area network (LAN) connects computers within a limited area, such as a house. In this case, all computers in each room connect to a central router, which fits the definition of a LAN due to its small geographical scope and direct connection to the networking hardware.
Step 2
Tick (✓) one box in each row to identify if the description is more appropriate for Ethernet or WiFi.
Answer
| Description | Ethernet | WiFi |
|---|---|---|
| A wired connection | ✓ | |
| More likely to be affected by interference | ✓ | |
| Data can be transmitted at a faster speed | ✓ | |
| Wireless transmission | ✓ | |
| Shorter transmission range before data is lost | ✓ |
Step 3
Describe the purpose of the router in the house’s network.
Answer
The router is responsible for directing data packets between the computers in the house and the internet. It manages local traffic, assigns IP addresses to devices, and maintains a secure connection to external networks. This device acts as a centralized point where all communication within the house’s network occurs.
