No CD-ROM means Compact Disc Read-Only Memory. CD-ROM is an input device. However, CD-RW (Compact Disc Read Write) is both a input and output device.
It is both an input and output device
Those would probably not be considered an "output" device. CD rom and compact disc are the same thing (CD stands for "Compact Disc").
A CD-ROM (using a player) is an input device because it holds information that is readable. There are writable and re-writable CD's which allow you to add or remove information making it an output device (storage device) as well.
I would say that a CD-ROM is a form of input, as it is "read only memory" and the data on it can only be read, but not written to. If you're talking about CD-R/CD+R drives, then those would be considered both input and output, as it can read from a CD, and writes to CD.
