The lecture covers several standards. Which ones are most common? Which ones are more or less obsolete? What can you find out about the future of transmission and media types? What is happening with 10 Gbps? What about 100 Gbps? What environmental factors would you commonly take into account when choosing which media to implement in a given situation?

Most common transmission media today is fiber optics and the many variables of twisted pair copper cable. When discussing environmental factors everything is in risk mitigation. What I mean by this is that you really wouldn’t connect two routers together with copper cable, the amount of data and the speed required to have a good network just isn’t there with copper cable, thus you would use fiber optics. Then we discuss copper cable or twisted pair as it is most commonly know these days; coax is more for just your cable TV these days. So for twisted pair you have to know where the cable is being placed, do you need plenum cable or not. If you are running cable through the floor or wall then it is mostly required to be plenum, plenum means the space between the floor and walls and in cable terms it also means the cable is fire rated. Then you could use non-plenum cable to hook up the computer to the wall socket for connection. Are you concerned with security, then you would use shielded twisted pair and if security isn’t a large concern you can use un-shielded twisted pair. There are price challenges with each cable selection and possible training issue with the installation of a particular cable. Will CAT 5 cable suit your needs or should you purchase the CAT 6 cable. CAT 6 is certified for Gigabit networking and will show better performance within longer distances…
