However some CRTs were used in input devices as flying spot scanners to scan microfilm documents into the computer. This function has generally been replaced by LASER scanners, which can be used on opaque documents that the CRT could not scan.
A CRT or cathode-ray tube monitor is an output device. Think of the big, bulky, heavy monitors that you can still find used in older setups today. Rendered almost obsolete by the more current flat screen monitor, CRT's were the industry standard for some time and are still used by many around the world.
