- [Instructor] When it comes to network cabling…in today's world, one of the most common forms of cabling…that you'll find out there is…what's known as a copper cable,…and to be more specific,…it's what's commonly referred to as twisted pair cabling.…So let's talk about that here.…So the way that twisted pair cabling is made up is,…it's made up of a series of eight wires.…So if you look at the picture in the top-left,…you'll see what looks like four wires coming out of a cable.…
And what this picture is,…this is basically if we clipped off the end…and stripped back the outer shielding,…this is what you'd see, the actual wires.…There's eight of them, but they're twisted in pairs,…which is why it looks almost like…there's four wires coming out.…Okay, but those are each pairs of wires and they're twisted.…Now, why are they twisted?…Well, electrical engineering 101 is that,…when you have two wires running parallel to each other…and they both have a signal transmitting,…they have energy transmitting across them,…you get waves, and those waves,…
