Computer Science Homework Help

Can you help me understand this Cyber Security question?

The proliferation of the Internet of Things (interconnected devices, primarily using wifi as the means of communication) means that most individuals will be using a wifi network or be exposed to wifi networks on a daily basis. Reflect on the following:

1. What risks and safeguards are associated with wireless communication?
2. Are you comfortable (or would you use) a wireless “hot spot” to do computer work?
3. What safeguards might you use in accessing an unprotected (public) wireless communications?
4. Are you more at risk using a wireless connection via laptop or a connection via a smart phone?

For the curious, take a look at What is “war driving” or “war flying.” How prevalent are these two terms today?
