Subtitles of the Movie (CompTIA Network+ (2009 Objectives) / Ethernet Basics / Gigabit Ethernet)
Gigabit Ethernet came along after fast Ethernet and this is fast Ethernet on steroids and there are two types of gigabit Ethernet that you will need to understand for the Network+ Exam. They are listed in their Objectives. The first one is called 1000Base-T and you can pretty much guess what this is. Now notice this uses Category 5, 5E, or Category 6 Twisted Pair cabling. Now the general rule is when you're installing new cable put the, kind of the top of the line out there, you would go with Category 6 now. And the different cabling that you have, kind of the later the better generally your service is and the more speed and distance you get, but anyway, you have a maximum distance here. Again, we're still Twisted Pair, we're still copper, so it's 100 meters roughly around 300 feet, 330 feet, something like that. But notice we can transfer data at 1000 megabits per second which translates to 1 gigabit per second. And again, we're 10 times faster than fast Ethernet which was 10 times faster than standard Ethernet. And again, we have changed the way we can use our networks here drastically. Now 1000Base-X uses Fiber Optic cabling. Notice what happens to the distance here. We have a maximum distance of 70 kilometers, which means roughly somewhere around 40 miles. That's quite a distance to be able to pass data at 1000 megabits per second or, again, 1 gigabit per second. Now gigabit Ethernet is, still as of the time of doing this video, gigabit Ethernet is standard with a lot of companies but still coming into play with a lot of companies. I wouldn't say that gigabit Ethernet is the standard in place, but it is certainly the standard for new installations and so forth now because think about how we're using our networks - voice-over IP, a lot of video, a lot of audio files, a lot more network-intensive or space-intensive, network utilization-intensive data is being passed through our networks and there's just a lot more people on our networks. Everybody has hand-held devices, PCs, and so forth on their desk and even most of our appliances and everything now connects to Ethernet so, to the Internet and goes through Ethernet, but anyway, gigabit Ethernet continues to kind of push the envelope on speed and this really is probably the new standard for the base level of where you want to go with your networking. Now by the time you get this video and it's finished and out there in production we will probably blow past gigabit Ethernet, and coming up in the next movie or so I'll show you where we're going next, but for now these are the two types of gigabit Ethernet you need to be familiar with for the Network+ Exam.
