Why does wireless networking face interference issues?

Wireless networks often experience interference. What is the main reason for this?

A Because wireless networks use cables that can get damaged

B Because wireless signals share the air with many other devices and obstacles

C Because wireless networks require more power than wired networks

D Because wireless signals travel only in straight lines without bending

💡 Hint

Think about what else uses the airwaves besides wireless networks.

Wireless signals travel through the air and can be disrupted by other devices, walls, and physical obstacles, causing interference.

📋 Factual

intermediate

What limits the range of wireless networks?

Which factor primarily limits how far a wireless signal can travel effectively?

A The power of the wireless signal and physical obstructions

B The length of the network cable

C The number of connected devices

D The speed of the internet connection

💡 Hint

Consider what affects signal strength and obstacles in the environment.

The power of the wireless signal and physical obstacles like walls reduce the effective range of wireless networks.

How does mobility create challenges in wireless networking?

Why does the ability to move devices freely cause unique challenges for wireless networks?

A Because mobility increases the speed of data transfer

B Because moving devices require more cables to stay connected

C Because moving devices can cause frequent changes in signal strength and connection quality

D Because mobile devices cannot connect to wireless networks

💡 Hint

Think about what happens when a device moves away from or behind obstacles.

When devices move, the wireless signal strength can change often, causing connection drops or slower speeds.

Compare security challenges in wireless vs wired networks

Which statement best explains why wireless networks have more security challenges than wired networks?

A Wired networks cannot be hacked

B Wired networks are always encrypted, wireless are not

C Wireless networks do not use passwords, wired networks do

D Wireless signals can be intercepted by anyone within range, unlike wired signals confined to cables

💡 Hint

Think about how data travels physically in both types of networks.

Wireless signals travel through the air and can be captured by unauthorized users nearby, making security harder to maintain.

❓ Reasoning

Why is managing wireless network capacity more complex?

Wireless networks often have to manage many devices sharing the same airwaves. Why does this make capacity management more complex than wired networks?

A Because wireless devices compete for limited airwave space causing collisions and delays

B Because wired networks have unlimited bandwidth

C Because wireless networks do not use routers

D Because wired networks cannot connect multiple devices

💡 Hint

Consider how multiple devices communicate over the same medium in wireless networks.

In wireless networks, many devices share the same frequency space, leading to competition, collisions, and delays, which complicates capacity management.
