Grade 10 Networks Quiz

What is the primary difference between a Wireless LAN (WLAN) and a wired LAN?

• WLANs use cables for communication, while wired LANs do not.

• WLANs use radio or infrared signals for communication, while wired LANs use cables.

• WLANs are used over longer distances compared to wired LANs.

• WLANs are more secure than wired LANs.

Which device in a WLAN connects wireless devices to the wired network?

• Router

• Modem

• Access Point (AP)

• Switch

What technology do most commercial WLANs use to extend the network range?

• Infrared technology

• Ethernet cables

• Spread-spectrum technology

• Fiber optics

What is one major limitation of using infrared technology in WLANs?

• Infrared has a very short range and is easily blocked.

• Infrared signals can penetrate thick walls.

• Infrared supports long-distance communication.

• Infrared is more reliable than radio signals.

Which of the following is NOT a disadvantage of wireless networking compared to wired networking?

• Subject to interference from external sources

• Easier to expand the network without cables

• Data is less secure and easier to intercept

• Signals can be stopped by thick walls

What is the typical range for spread-spectrum technology used in WLANs?

• 1–2 meters

• 10–20 meters

• 30–50 meters

• 100–200 meters

Which of the following is an advantage of using WLANs over wired LANs?

• Faster data transfer rates

• Increased mobility of devices within the network

• Lower chance of signal interference

• More secure data transmission

Why is data transmission in WLANs considered less secure than in wired LANs?

• It is easier to intercept radio waves and microwaves than cables.

• Wired networks have no security vulnerabilities.

• WLANs do not use encryption for data transmission.

• WLANs use weaker passwords for authentication.

What is the primary advantage of using Wireless LANs (WLANs) over wired LANs?
