💡 Hint

Common Mistakes

Choosing 'routers' because they are part of the network, but they don't block signals.

Choosing 'cables' which are not related to wireless signals.

Obstacles like walls or furniture can block or weaken wireless signals, making networking less reliable.

2fill in blank

medium

Complete the sentence to describe a factor that affects wireless network performance.

Computer Networks

Wireless networks can suffer from [1] when many devices try to use the same frequency at once.

Aencryption

Bspeed

Cdistance

Dinterference

Attempts:

💡 Hint

Common Mistakes

Choosing 'speed' which is an effect, not the cause.

Choosing 'encryption' which is about security, not signal quality.

Interference happens when many devices use the same frequency, causing signal problems and slower connections.

3fill in blank

hard

Fix the error in the sentence about wireless network range.

Computer Networks

The effective range of a wireless network is limited by [1] loss, which weakens the signal over distance.

Asignal

Bpower

Cattenuation

Dbandwidth

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'power' which is related but not the correct term.

Choosing 'bandwidth' which refers to data capacity, not signal loss.

Attenuation is the correct term for the loss of signal strength as it travels through space or obstacles.

4fill in blank

hard

Fill both blanks to complete the explanation about wireless security challenges.

Computer Networks

Wireless networks are more vulnerable to [1] because signals can be [2] outside the physical building.

Aeavesdropping

Bencrypted

Cdetected

Dhacked

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'encrypted' which is a security measure, not a vulnerability.

Choosing 'hacked' which is a general term but less precise here.

Eavesdropping means unauthorized listening to wireless signals, which can be detected outside the building because wireless signals travel through walls.

5fill in blank

hard

Fill all three blanks to complete the dictionary comprehension about wireless network factors.

Computer Networks

factors = { [1]: [2] for [3] in ['interference', 'range', 'security'] }

Drag options to blanks, or click blank then click option'

Bimportance

Ditem

💡 Hint

Common Mistakes

Using the same variable name for key and value.

Using a word not related to iteration for the loop variable.

This dictionary comprehension creates a dictionary where each 'factor' is a key and its 'importance' is the value, iterating over each 'item' in the list.
