A: LED will have a visual greater real estate on the cathode side it can be seen if the LED is transparent other way is using a VOM and measure the potential . the less potential will be at the cathode.
CRT for Cathode Ray Tube
crts (abbreviation for cathode ray tubes)
THE MATERIALS USED TO MAKE THE FIRST pC IN THE XEROX LABRORATORY WERE ALUMINUM, PLASTICE, GLASS , AND CATHODE RAYS
Cathode Ray Oscilloscope - referring to the display component itself (cathode ray tube, as used to be used on televisions and computer monitors). Most oscilloscopes now use l.c.d. monitors; or can be synthesised on a PC with suitable software.
How and where you connect a LED to a PC largely depends on the application. More specifically, is it to indicate for instance, that a hard drive is running or that the power has been turned on? For those types of applications a visible LED would be your best choice. For remote connection applications like PC to PC use, then most likely it would be a combination of infrared LED's or more commonly called IRED's. This may or may not also involve an IRED diode for the receiving part of the communications.
Either the LED has blown (like all lights, LED's blow, too), or it has been disconnected
might refer to the abbreviated CRT meaning "Cathode Ray Tube" which were the box looking TVs and PC Monitors back then.

A single board microcomputer is a microcomputer built on a single board. There are no plug-in boards required, though they might be optional. Most modern PC's are single board, if you ignore the fact that some of the parts, such as the RAM, are plugged in.
If your issue is all sounds not working then, check with the website for the manufacturer of your mother board, for drivers/updates.
