For understanding computer networking, Computer networks by Andrew Tanenbaum: http://www.amazon.co.uk/Computer-Networks-Andrew-S-Tanenbaum...
For physics (though old now), Feynman's lectures: http://www.amazon.co.uk/Feynman-Lectures-Physics-boxed-set/d...
For a more in-depth discussion of physics, I’ve found the Feynman Lectures [1,2] to be quite enjoyable. It’s a long read (I’ve only finished the first book) but it is very thorough.

If it was possible to transmit classical information faster than light, this would violate causality as we understand it (you could receive a message that you had been shot before you actually experienced being shot, thus allowing you to prevent yourself from being shot). It's a bit difficult to understand why this is true without a solid understanding of relativity, but you can read up on it a bit here http://en.wikipedia.org/wiki/Special_relativity#Causality_an....
This is all heavy stuff and very non-intuitive, but if you're curious about it and eager to learn I'd highly recommend this tome: http://www.amazon.com/The-Feynman-Lectures-Physics-boxed/dp/...
(serious reply, if it's insufficient for a freshman course i propose following up with Feynman https://www.amazon.com/Feynman-Lectures-Physics-boxed-set/dp..., any objections?)
