The complexity of setting up a network

The use of multiple routers for security

What is one reason why ad-hoc networks typically have slower performance compared to traditional networks?

Devices in ad-hoc mode only support slower transfer speeds

They use faster transfer speeds

They have more advanced hardware

They use only wired connections

Why are ad-hoc networks generally considered to have weaker security?

Wireless connections are commonly used and there is no central device for security management

They use only wired connections

They have a central device managing security

They use the latest encryption methods

Which of the following best explains why wireless connections in ad-hoc networks are less secure than wired ones?

Wireless connections are easier to intercept and lack centralized security management

Wireless connections are always faster

Wired connections are more vulnerable to attacks

Wired connections do not require passwords

Suppose you are setting up a network for a group project. If you choose an ad-hoc network, what are two main disadvantages you should consider, and how might they impact your project?

Slower performance and weaker security, which could lead to slow file transfers and increased risk of unauthorized access

Higher cost and complex setup, which could make the project expensive and difficult to manage

Limited device compatibility and lack of internet access, which could prevent some members from joining

Excessive power consumption and frequent disconnections, which could disrupt communication

What is a major security risk associated with open networks?

Lack of encryption and password protection

Too many users connected at once

What does encryption do to your data?

Makes it unreadable to unauthorized users

Why are open networks more susceptible to unauthorized access and misuse?

They lack security mechanisms found in password-protected networks

They have faster internet speeds

They are only used by trusted users

Explain why using an open network without encryption can be risky for users.

Data can be intercepted and read by unauthorized people

The network will run out of bandwidth

The internet connection will be lost

Which of the following best describes "data interception" on an open network?

An attacker can easily intercept the data you send and receive, including sensitive information.

An attacker can only access public information on the network.

An attacker can only slow down your internet speed.

An attacker can only see the websites you visit, not your data.

What is one risk of using open networks related to malware?

Attackers can use open networks to distribute malware and infect connected devices.

Open networks automatically remove malware from your device.

Open networks prevent malware from spreading.

Malware cannot be transmitted over open networks.

How can attackers exploit open networks to gain unauthorised access?

By bypassing security barriers and manipulating data and settings on your device.

By improving your network speed.

By providing free antivirus software.

Suppose you are using an open network in a public place. Which of the following actions would best reduce your risk of data interception?

Using a virtual private network (VPN) to encrypt your data.

Sharing your passwords with friends.

Downloading files from unknown sources.

Turning off your device’s firewall.

What is a major limitation of ad-hoc networks?

They are always faster than infrastructure networks.

They use only wired connections.

They do not require any devices to connect.

Why can't ad-hoc networks transfer data as fast as networks in infrastructure mode?

They have a smaller maximum data transfer speed.

How do wireless routers compare to ad-hoc networks in terms of range?

Wireless routers provide much greater ranges.

Ad-hoc networks have a greater range.

Ad-hoc networks use satellites for range.

How does interference in ad-hoc networks affect data transfer?

It increases the corruption of data being transferred.

It makes data transfer more secure.

It speeds up the data transfer process.

It prevents devices from connecting.

Why do ad-hoc networks produce more interference compared to other networks?

Each device has its own connection and devices often move around, crossing signals.

They use only wired connections.

They have fewer devices connected.

They use a single, fixed connection point.

Why are network connections not equal across the entire world?

Because of differences in network location, infrastructure, and country development

Because everyone uses the same devices

Because all countries have the same technology

Because the Internet is only available in cities

Which issue is specifically related to the performance of both mobile and traditional broadband for end users?

Number of social media accounts

Explain how the location of a network can affect its availability and performance.

The location can impact signal strength, infrastructure access, and exposure to blackspots.

The location determines the color of the network cables.

The location only affects the price of the network.

The location is not important for network performance.

What is one reason why rural areas may have poorer internet speeds compared to cities?

Fewer phone masts and less access to superfast broadband

More phone masts and better broadband

More investment from telecom providers

Why might you experience more internet dropouts with mobile broadband in rural areas?

There are fewer phone masts and weaker network coverage

The internet is not needed in rural areas

Explain how the location of a network can impact the quality of broadband and mobile internet services. Use evidence from the text to support your answer.

Cities have better coverage due to higher investment and more infrastructure, while rural areas have poorer speeds and more dropouts due to less investment and fewer phone masts.

Rural areas always have better internet because they are quieter.

The location does not affect network quality at all.

Only the type of device matters for internet quality.

Which of the following is most likely true about network coverage in developed countries compared to developing countries?

Developed countries have better network coverage due to more investment in infrastructure.

Developing countries have better network coverage due to more advanced technology.

Both developed and developing countries have the same level of network coverage.

Developed countries lack the resources to invest in network infrastructure.

Why do developing countries often struggle to provide modern broadband speeds across their entire country?

They lack enough money devoted to network infrastructure.

They have too many users on the network.

They have outdated laws preventing broadband use.

They focus only on rural areas for network coverage.

According to the text, what do the red areas in the image represent?

The availability of 4G broadband.

The areas with the slowest internet speeds.

The regions with the highest population density.
