Part 1 of 2 in the Microsoft MTA: Networking Fundamentals series. If you're at all interested in computing technologies, you probably find yourself asking what is a network or what exactly is a protocol? Beginners in the computer world looking to actually start working with computer networks should be building up a technical background with computer networking standards. This course is designed for those who have little to no experience in networking, but want to learn solid skills to build upon.

Getting Started with Networking Fundamentals Well, hello there. My name is Ed Liberman and I'd like to welcome you to Train Signal and our course on Networking Fundamentals. You're watching the first lesson of this course called Getting Started with Networking Fundamentals. In this first lesson I'm going to start off by telling you a little bit about myself. Then I will explain to you what exactly we'll be doing in the course and what all the topics are that we're going to cover and then I'll wrap things up by giving you a few tips and tricks that hopefully will help you to get the most use out of this course.
Basic Networking Fundamentals Welcome to Train Signal. You're watching a lesson on Basic Networking Fundamentals. Now you may have noticed that the name of the course is Networking Fundamentals and here the name of this lesson is Basic Networking Fundamentals and that's exactly what it is, okay? This is going to just kind of lay the groundwork for everything else we're going to cover in this course. I'm going to talk to you about the really, really, really high-end stuff like starting off with what exactly is a network, right? Because you can't really learn about networking fundamentals if you don't know what a network is. We'll look at the different types of networks, how we make connections, what protocols are, and I'll give you a brief introduction into IP addressing and speaking of brief introduction, I will tell you that pretty much across the board everything in this lesson is going to be a brief introduction to the stuff that we're going to go into more detail later in the course.
Wired Network Media Welcome to Train Signal. You're watching a lesson on Wired Network Media. In this lesson, well we're going to talk about, you guessed it, wired network media. That includes twisted pair, coaxial, and fiber optic cables. We'll talk about something called the Plenum. We'll look at some of the connectors that are used with those cables. I'll go over some of the wiring standards and we'll wrap things up by talking about some LAN technology types.
Network Topologies Welcome to Train Signal. You're watching a lesson on Network Topologies. In this lesson we'll start off by defining exactly what a topology is. We'll take a look at some of the physical network topologies that are used. We'll go over some WAN technologies. Earlier in this course we talked about LANs versus WANs and we've already talked about some of the typical LAN technologies that are used. Well now we'll take a look at some of the WAN technologies. We'll look at something called VPN or virtual private networks and then we'll look at something called VLAN, which is virtual LAN or virtual local area network.
OSI Model Welcome to Train Signal. You're watching a lesson on the OSI model. In this lesson we're going to start off by going back and reviewing the definition of a protocol. Now this is something that I mentioned earlier in the course, but here we're going to go through it in a little bit more detail and make sure we have a good, firm understanding of exactly what a protocol is. Then we'll go through and talk about the different layers of this thing that you may have heard of, it's something that's talked about a lot but not many people really know what it is, this thing called the OSI model. So first of all, to get things started as I mentioned, we need to go back and make sure that we're solid on our understanding of a protocol. Now if you look up the definition of the word protocol, it's a set of rules and procedures used for communication, but what exactly does that mean? A set of rules and procedures for communication? Well let me try to explain it in a little more detail by using an example.
TCP/IP Communication Welcome to Train Signal. You're watching a lesson on TCP/IP Communication. In this lesson we're going to start off by going through something called the TCP/IP protocol suite. We learned in a previous lesson that a protocol is a set of rules and procedures for communication, but that the reality is that each protocol is actually made up of many smaller more, granular protocols all put together to make that one protocol or what really should be called a protocol suite. So we're going to go through the TCP/IP protocol suite and in that suite we are going to talk about in more detail the transport layer protocols and the internet layer protocols, okay? So these are protocols that are found within that suite. We'll look at different types of communication that takes place on a TCP/IP network and we'll look at some different access methods.
IP Addressing Welcome to Train Signal. You're watching a lesson on IP Addressing. Now in this lesson, well you guessed it; we're going to talk all about IP addressing. We're going to see how to work with IP addresses. We're going to talk about planning out an IP addressing scheme. We then have to see how to take our IP addresses the way we normally see them and see how they work in binary fashion, so you're going to get a little bit of a math lesson, but don't freak out. I promise, I make my math lessons very, very simple. We'll talk about something called internetworking, which is where we have computers with IP addresses on different networks being able to talk to one another, and then we'll wrap things up by talking about the difference between classful versus classless interdomain routing.
TCP/IP Command Line Tools Welcome to Train Signal. You're watching a lesson on TCP/IP Command Line Tools. Now in this lesson, well you guessed it. We're going to look at some command line tools. Now I have them all listed here and I don't want you to be confused by all the different slashes. I just kind of grouped a bunch of the tools together, so if I just kind of go through the whole list, all the tools we're going to look at are IPCONFIG, ARP, ROUTE, PING, Tracert, PATHPING, NETSTAT, NBSTAT, NSLOOKUP, TELNET, FTP, and NETSH, okay? So these are all the tools that we're going to talk about in this lesson and actually, we're going to jump over to a Windows operating system and see how some of these tools actually work.
