Hi, My name is Tyler McMinn, and welcome to our series on networking basics. In this first video, what I want to do is discuss what type of network you're using in your house to get connected and really try and understand what's involved with getting online, getting to the Internet, getting to your printer and working or just using the network amongst a bunch of other devices that might actually be at your house. So what we're going to look at is what I'm using in my house to get online and get connected, explaining some of the terms that are involved, how you can look at your own addressing your own switch or router or access point or, in most cases, all of the above as one device to get online. So let's take a look here. We first need to wrap our heads around what exactly is a switch network here? And a switch network or computing network is defined as well they say it here a group of computing resource is that permit digital data between devices. So what type of devices? In English what that basically means is you're connecting your laptop to another device printer or a server or the Internet. And to get there, you're going to need to send your data along some sort of network, beating a cable or radio and talk to the network. Talk to that server talk to everyone, every device in between in a language or using protocols that everybody understands. So there's a bit of standardization that we want to abide by. So if you take a look at your home network here, you might be sending data along a network cable. So there's a little truckload of data going to some sort of switch or router or wireless access point to be able to carry your data out to the edge of what is your house or your homes network. At the edge of our network we don't actually have our own dropped to this big corporate interchanges that you would use. Instead, we lease or rent access through a service provider, and the provider would either allow us to use our own modem or they would lease one to us as well. But what we're really paying for with our monthly service to the Internet is we're paying for access to the Internet that the service provider provides. That's the main job of most Internet service providers here. So whatever service provider you're using, they'll have some sort of connection from the street or, a hub to get to your home. And then, from there you'll be able to access at whatever speeds that they provide using your own connection. And most of these are going to be utilizing in some sort of Ethernet cable, going from your own modem or your own router, your house a switch router access point type of concoction. Here we'll take a look at one in more detail in just a second, but that needs to get some sort of access. And the access in this case is being provided by a modem, otherwise known as a modulator D modulator. To be able to handle whatever type of connection the service provider wants to run to your house, whether it's thick coax cable from a cable provider, whether it's a DSL connection, which runs over the old phone lines that ran to your house for that technology has been around for 100 years, or whether it's fiber that you're running from the street. This is more of a common solution that we're seeing out there nowadays with fiber running to your homes. So let's dive in and actually take a look at my own house and how I'm actually getting connectivity. And if you take a peek here first thing, we want to demonstrate just how we actually get online. Where will describe what exactly, is an IP address and then connecting to the access point itself. So the first thing is just on your own computer. You could do this while watching the video. I'll show you right here if you open up your network connections and this could be found by opening up the control panel of your operating system or looking at the preferences if you're on an Apple device, I'm on a Windows PC. So in most of these operating systems, if you just simply open up the command option or the Windows key, you can start typing things. So I'm going to type the command control panel and I'll see the control panel app pop up. Here's my control panel right there, and in this you can go down to network and Internet. So I'm going to open that up then to network and sharing center. I'll click that and look at that. I've got the options to set up a new connection, but it shows me I'm currently connected to my home network and there is an Ethernet connection. So if I were to click on this little Ethernet icon, it gives me my network details my IP address, my subnet mask and my gateway. So if you're on a windows computer and you want to go ahead and look at this using a command prompt, to open this up you simply hit the Windows key, which says the little windows icon next to the space bar and the old key there's this little windows key and type the letters C M D. And what you're going to see is it will pop open this command prompt here for you. If you're on Apple, open the terminal option. And on Lenox, same thing. You can open the terminal and issue your commands, which is fine. We're going to be working with predominantly Windows commands for this class. But it won't really matter too much because we're going to be in the CS operating system. So if I pop in with the command prompt, you can see the results which are on the slide. But what I did was I typed the command, Ipconfig and Ipconfig will open this up in Windows. The equivalent would be, if config if you're on a Mac or Linux machine, but in windows boom. And from that you can see all those adapters I had. I may have to scroll up or move the little cursor on the side here to get to the top. And there is my Ethernet adapter with my IP address, my subnet mask and my gateway all listed there for you and what we're not going to get too much into these. It's important to note that the IP address is what my computer in my house has uniquely compared to all the other machines and computers running in my home. And then we all share this common gateway this doorway to get to the modem and to get out of our house. So that means that I should be online. And I'm just pressing Enter to get a new line here. But I can ping or type a command to test my own IP address. And I should get my responses from myself or what we call echoes or replies. And I can also ping my gateway to validate that I could reach it and see if I'm getting responses back. What you're seeing here is you're actually seeing the ping to the gateway go forward and you see it pings four times with replies each and every time. The first thing you're going to want to do to get connected and get your addressing and to take advantage of these services is plug in the network cable. Or alternatively, you can fire up your radio. Actually do have a wireless adapter plugged in here. So if I were to disable my network card, which don't do in your own computer, I could then open up my wireless card. And now I've got the option to connect or disconnect to a wireless network. So I'll just simply double click to reconnect there, and I can disable the wireless for now, since I'm not really using it. And there you go, up and I'm online and I'm good. At my particular house I'm just using a normal retailer type of wireless access point. In the enterprise world you might use, for example, one of these Aruba APs to work from home, or one of the different models that would actually hang on the ceiling there. Again you could look at those through that little three d tool I showed you, but we want to take a look at this home network. So all you do is you put in the IP address of your device for my home. You might have a different one as your gateway admin and then whatever the password is, so the user name and password for your little home router there, of course, you want to make sure that you put it in directly. There we go, and it's loading up this interface to work with my home router, my home access point. You could see the Internet's good. I've got a wireless connection available, and I have a bunch of attached devices. If I actually click on attach devices, you could see I have a lot of attached devices in my house that are not actually using the radio on that access point because I actually have to access points. So it's a long story. But point being is that each of these devices has a unique IP address and unique Mac address so that there's never a conflict, even though they're on the same network, the same local area network. In fact, you need to make sure that those two things are correct, are unique IP address and Mac address. But every single one of these devices is using the same Internet address or the same gateway address that this particular router is providing. So if I look my IP address for this router is 1 or 2168.1, and then I'm connecting to my modem, which is offering its own address. And that could be either a public address or the modem itself might also have a private address facing you and a public address facing the rest of the Internet. So that's going to wrap up our introduction of what your home network may look like and how to navigate that network to understand more about it. In the next video, we're going to dive into what an enterprise which may look like such as this Aruba 63 100 m kind of play around with that there. And I'm going to discuss what exactly are the components of this? How that differs from your home network? And then we'll dive into a bit of discussion on encapsulation and to actually getting your traffic to go from point A to point B in this first part series. So thanks very much for your time. I'll see you guys in the next video.
