1) ____ is an abbreviation that refers to the number of times a wave oscillates per second.
2) A ____ network makes use of a building's existing telephone cables to connect network devices.
3)A ____ contains circuitry that converts the data-carrying signals from your computer to signals that can travel over various communications channels.

1. Frequency.
2. I have no idea what network. I know that RJ11 is a telephone cable type and RJ45 is the ethernet cable type, but what type of network? I have no idea.
3. switch (I think)

Those questions are rather vague.

I'd doublecheck what chapter you are on to verify.
