Basic Networking Fundamentals
Welcome to Trainsignal. You're watching a lesson on basic networking fundamentals. Now in this lesson, I will tell you, well just like the title says, this is going to be very basic networking fundamentals or really just kind of the foundation of everything else that we're going to cover in this course. So you might actually feel as we go through this lesson like I'm teasing you, like I must just give you just a little tidbit of information, just enough to kind of salivate your mouth and be like, oh okay now I want to know about that, just in time for me to say, but that's all I'm going to give you right now. And why am I doing that? Well, I like to be mean. No, all kidding aside, the reason I'm doing that is because I need to give you these little tidbits of information so that you can have them in the back of your mind as you learn the details of these different technologies as we go through the course. Okay, there's a lot of these technologies that rely on one of another and so there's kind of that dilemma of how do I learn this when I need to learn this first, but in order to learn this I have to learn this first. Okay, so I'm going to give you all these small little pieces of, you know, all the different technologies so that it will allow you to really get it all to soak in as we go through the rest of the course. So that said, let's go ahead and get started.

Terminating a CAT 5 Cable
Welcome to Trainsignal. You're watching a lesson on terminating a CAT 5 cable and in this lesson that's exactly what we're going to do. I'm going to show you exactly how to terminate that RJ-45 jack onto a CAT 5 twisted pair cable, but before we do that let's go ahead and make sure we're clear on the wiring standards.

Network Topologies
Welcome to Trainsignal. You're watching a lesson on network topologies. Now in this lesson we're not only going to go through the various networking topologies that are available, but we're also going to talk about some WAN technologies. Let's go ahead and get started.

OSI Model
Welcome to Trainsignal. You're watching a lesson on the OSI model. In this lesson there are two main things that we're going to talk about. Number one, we need to learn what a protocol is and then that is going to allow us to learn about the OSI model. So let's go ahead and get started.

IP Addresses
Welcome to Trainsignal. You're watching a lesson on IP addresses. Now I'm sure you've heard that term, IP address before. As a matter of fact, I'm pretty certain I've probably already used that term many times throughout this course. Well in this lesson we're going to go ahead and make sure that you fully understand exactly what an IP address is.

Binary Math
Welcome to Trainsignal. You're watching a lesson on binary math. Yes that's right, I said binary math. I'm really sorry. I know a lot of people really don't like those math lessons, but you're going to have take this one. This is something that goes to help you to understand a lot of the other IP addressing related subjects that we talk about in this course. The one thing I do promise you is that in this lesson I'm going to teach you a very easy way to understand binary math.

Subnetting
Welcome to Trainsignal. You're watching a lesson on subnetting. Now in previous lessons we've learned about things like networks and we've learned about IP addresses and we've seen just a little bit about how maybe those go together. Well in this lesson we're going to see how we can take a network and subdivide it into sub-networks.
