Hello everyone.
This is an introduction to networking.
Now this isn't really networking because this is an addendum to everything that we do in farming Dale's
course because he has to 62.
So there is a lot of relating things to networks to networking but we're really focusing on all the
things that aren't in the book etc. So we're going to be covering a lot of principles that are necessary
to be aware of and know but not necessarily things that are the details of that works as you might expect.
So for instance you do have to be very familiar with things like digital principles and you're going
to have to get familiar with my terrible terrible writing as well.
Digital principles.
But that means that we need to learn about binary because that's necessary to understand about network.
This is really shall we say background for networking because there's a lot of things that you can't
really understand.
You know things like that.
You do have to understand things about logic tables and truth tables and charts because that's how the
bottom layer of the OCI model the or maybe one follow up.
But the bottom layer the hardware and all that is working so you've got to understand how that works
which means we have to talk about all these ideas that are related to that.
We have to talk about stuff related to compression and sending messages to stuff about digital security.
Stuff about all kinds of relationships that exist in the seven Esai levels.
So you have different levels where you have the hardware and you have the software that talks then you
send the message.
But each of these levels requires a lot of different protocols and step.
So for instance if you're trying to send the message you have to convert it.
Well that's important to understand what it is we're converting from digital to analog etc. We have
to understand all these background information.
So this really is a bit of background to networking and trying to understand the foundations that we
have to set.
Set everything up.
The course is you know a bunch videos a bunch of questions.
It's here to give you more examples of stuff that in class we would really be discussing.
And it's it's like I said I'm not here to discuss the levels although maybe I'll get into it.
You know it's really to discuss all the things that are that are important in the levels like for instance
compression compressing data you know how do we send that across.
We have to compress it you know and we have to also check about error correcting and detecting codes.
That's very important as well.
So all of these things are the foundations to it.
More details than would necessarily be covered in your typical course.
And that's why it's here to give you a greater understanding of everything that's out there.
So hopefully everything will go well and you'll learn a lot and get familiar with it and see more examples
and more background and be much better off.
So good luck and hopefully everything will go well.
