dvd rom is a out put device
It is both an input and output device
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.

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.
Input devices are computer devices that take in data and process it to display through output devices. A real time example of an input device is a DVD-ROM playing a movie and displaying the video on a Screen that acts as an output device.
It can be both, depending on where it is in the process. In most cases, it will be an output into another device, so it would be plugged into the input of the other item. In a typical cable TV set up, the cable would go into the input of the DVD and the output of the DVD would go to the input of the television.
A touchpad is an input device. It operates on the same principle as your mouse does, taking your movements or gestures and translating them into a form the computer can understand in order to get work done.
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.
A programmable electronic device that can input process output and store data means a microcontroller which has an inbuilt ram,rom and i/o's . A programmable electronic device that can input process output and store data means a microcontroller which has an inbuilt ram,rom and i/o's . -------------- although that sounds nice, the text book answer is "computer"
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.
