It is neither, CD DVD and hard disk is STORAGE not input or output.
No a disk drive is neither input or output device, it is an optical disk drive (for CD/DVD's) and a disk drive (for hard drives) would be a storage device.
No.
It's both. You can read the data on the disk making it an input device, and you can write data to the disk making it an output device.A floppy disk is a storage device. There is often confusion about this, as the user could be seen to be "inputting data" by inserting a disk or "outputting" by removing it, but in actuality the floppy disk is a storage device.
A microphone and a computer mouse has only an output. That is an input device. A loudspeaker and a printer has only an input. That is an output device. A read-write CD/DVD, floppy disk, tape drive, and hard drive are all I/O devices because they can be used to store and retrieve data.

input. Anything that gives information to your PC is input. The monitor or a printer is output.

no. You have processor, memory and input/output. Storage would be memory, hard drive, DVD.
If you are talking about off-the-shelf DVD players then it's an output device( display data read to video terminal [i.e. Projectors, TV's], but if you are talking about DVDRW devices then it's an input and output device. If you are talking about a DVD media, if it's just ordinary DVD-ROM then it's just input. But if you're talking about DVD-R or DVD-RW media then it's an input and output media.
