Question

Which of the following is not a mobile means of connecting devices to networks?

Answer 1

Answer:

USB cables.

Explanation:

Think of what would happen if you started walking to a friend's house that is 3 houses away from yours. You have a cell and there are no others that you can see. Your friend calls you.

Could you hear what he says with a blue tooth earphone? Likely.

If you are connected by a wifi device. Again likely.

What about a broad band. That would be possible too.

So what about a USB cable. Now there's a problem. The cable would have to be at least 75 feet long (city plots are usually somewhere in the neighborhood of 25 feet wide). You would need an awfully long cable. And that's only 3 houses away.
