Well first let's start on my progress. I am on the second to last chapter. After I'm through with it I'm going to go back and reread and test the concepts I still need a better grasp of.
So back to what I'm learning. Certifier, checks to make sure your network follows standards, costs a lot of money. Time-Domain REFLECTOMETER! It sends a signal down the a copper wire and if there's any interruption in the signal some of it will reflect back to the TDR. This allows you to check like speed of the wire, how much lost and cable length. Optical Time-Domain REFLECTOMETER performs the same function as the TDR except it's meant for fiber cables so instead of electric pulses it uses light and instead of measuring a response it measures the amount of scattered light. NEW PARAGRAPH.
You all probably know what a multimeter is. It just measures voltage, current and resistance. A Toner Probe is a somewhat nifty device where you connect one probe to the end of a wire and then using the other probe you can find that same wire in a bundle of wires since it listens for the tone.
That was a bit of a boring post but don't worry! I have something else in store!.
