You are here 4 7 the colors matter So what’s with all the colors? The paired wires in a CAT-5 cable are colored for a reason. Each color has a specific meaning, and so does the solidity of the color. Orange and green wires send and receive data. The orange pair sends data, while the green pair receives data. The green pair receives data... while the orange pair sends data. The color solidity shows the wire polarity. If a wire is striped, then this means that it is positive. If a wire is solid, then the wire is negative.

We fixed the part of the cable that was visibly damaged, but that hasn’t gotten rid of the network problems. But what if the cable’s damaged elsewhere too? What if we can’t see which bit is damaged? Not all cable damage is visible from the outside. Even though we’ve fixed the part of the cable that’s visibly damaged, there may be further damage inside the cable. So how can we detect this sort of damage? To do that, we need to dig a bit deeper into how coaxial cables actually work. 26 Chapter 1 fixing physical networks Q: A: Do many organizations still use coaxial networks now?

Think about how you think. Learn how you learn. Most of us did not take courses on metacognition or learning theory when we were growing up. We were expected to learn, but rarely taught to learn. I wonder how I can trick my brain into remembering this stuff... But we assume that if you’re holding this book, you really want to learn networking. And you probably don’t want to spend a lot of time. If you want to use what you read in this book, you need to remember what you read. And for that, you’ve got to understand it.
