Low stakes - Wired and Wireless Networks

1. Look at device A. What is this device?

• A hub
• A switch
• A router
• A client

2. Look at device A. What type of waves is it omitting?

• Micro waves
• Radio waves
• Router waves
• Radioactive waves

3. What is the name of the wireless technology device A is using?

• WIFI
• Bluetooth
• Ethernet
• Router

4, Which device is likely to have the best wireless connection to the router?

• B
• C
• D
• E

5. Why is the WIFI connection on device B likely to be worse than device E?

• There's other waves interfering
• Device B is slightly further away from the router than device E
• There is a floor in the way
• The router isn't very good quality

6. Device D is closer to the router, but its connection to the router is not as good as device Bs. Why is this the case?

• There's other waves interfering
• Device B is slightly further away from the router than device E
• Device D is outside
• Device D is upstairs - the floor between upstairs and downstairs will interfere

7. There is a microwave in the kitchen. Why will this affect the quality of the wireless connection between device C and the router?

• Other waves can interfer with the router's radiowaves
• It's far away
• The microwave will get in the way
• Device C is old and its WIFI is not good

8. Device G is connected to the router using a cable. What type of cable is it?

• Ethernet cable
• Router cable
• WIFI cable
• Fibre optic cable

9. Why has device G now get the best connection to the router?

• Signals travels through a cable - the radiowaves are stronger
• Signals travels through a cable - it's yellow
• Signals travels through a cable - no interference
• Signals travels through a cable - it will stretch over miles and miles

10. What advantage do all the other devices have over device G?

• The devices can be moved across the house without restriction
• Radiowaves are quicker
• Radiowaves can not be interfered with
• Radiowaves have a more reliable bandwidth
