How do devices and protocols keep data safe?

Most up to date devices can keep the majority of data safe, as they are very clever and they don't take a genius too work.
You can set your own password for security/protection.
On an iPhone you need a 4 digit code to unlock it that the owner can set. This can be very awkward and hard too guess as there are thousands of possibilities and the phone locks for 10+ minutes after ten wrong attempts.
On the iPhone you can download tracking devices and has a built in Satnav, this could be used too track your stolen phone. You can also have a password where it uses dots that you have to connect to each other.

On other phones like blackberries, you can set the password too whatever you like, including letters, so there will literally be billions upon billions of possibilities too keep your data safe.
You can also download tracking data and Satnav type apps on your blackberry too track a stolen phone etc!
Most Smartphones now-a-days can do things like this as they are clever devices!

There is also something called encryption; this is the process of sending a message privately so hackers and eavesdroppers cannot read it.

The difference between 3G and Wi-Fi I think Wi-Fi is faster because you have to be near it to be connected so it will have better connection and 3G I think will be slower because you could be anywhere and it might be a bit slower.

Bluethooth is also protected, because when you want to pair with someone you and them have to put a code in and keep your stuff safe. Wi-Fi is also safe because you also have to use a code to connect to that aswell.
