Finally, we have reached the bottom layer: let’s get physical! We will see how 1s and 0s can encoded into digital and analog signals for transmissions.

Kinky ah prof! Reminds me of this song: http://www.youtube.com/watch?gl=SG&v=vWz9VN40nCA&hl=en-GB
As computer science students, I guess we won’t be too bothered about the physical layer. After all, it is already into the electrical engineering domain. Having said that, things as simple as 0s and 1s can drive you crazy sometimes :).
I agree to some extent. It is still useful for a CS students to understand the basic principles though. (For instance, what does bandwidth really mean, why higher data rate leads to higher error rate, what does a modem do, etc.)
