A Twisted Pair? #JusJoJan

The only thing I can think of, at this late hour, for which the word "twisted" comes to mind, is twisted-pair cable. I took a class on the UNIX operating system a long time ago, and the instructor had a whole week to teach us everything he knew, and he used every minute of that time. He’d talk (and talk, and talk, and talk…) for eight hours, then we’d spend four hours doing these difficult exercises that had absolutely no practical application in what we would actually be doing. The guy was a nice guy, just a little too much into UNIX hardware and software, not to mention the Internet, which at that point was relatively new (I had gotten an America Online account not long before). He got into a very long discussion of the different types of cabling that were used to build networks, and one type was twisted-pair, where the wires within a cable were twisted in pairs to reduce the amount of electromagnetic interference. That was all he needed to say about it, understand…

And that’s all I’m going to say about it. You want to know more, check the Wikipedia article.
