Of course it could go both ways, but in our case
it's easiest to think about just one way communication,
and the other way is really just the reverse of that.
So in this case here, what we'll be talking about
is many, many different kinds of issues in this single source to destination
communication.
And we're going to be splitting this thing up
into a sequence of 11 different subtopics.
And the first part of the subtopics that we'll be talking about
are really these ones that are focusing on this link
over here, where what we're trying to do is take some kind of information
and send it to a remote location over something which is called the channel.
So for example, if I'm in the classroom, I
might be sending information over the air using my voice.
And in that case, there are several things
that might happen when I'm doing that.
For example, if I'm in a classroom situation,
even though I'm talking to you as the individual student,
some of your neighboring students might be doing something-- for example,
playing on their computers-- in which case
you might hear tapping of the keyboard, or they
might be talking to their friends, and whatnot.
And in that case here, you might get additional noise.
So we'll talk about the effect of noise on this channel
after we've discussed this initial link.
And what we'll see then is that the effect of noise
