A CD or DVD drive is a media device. Data is usually read from it, but data can also be sent to it if it has writing capabilities.
An interesting question. Typically, devices fall into a category of 'input' or 'output'. A monitor, for example, would universally be regarded as an output device. A keyboard, an input device. A platter, which I'm assuming is a hard drive platter and not a delicious halal meal, falls neatly into both catgeories. It is an input device when data is being read from it, and an output device where data is being read to it.
input device
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.
A: It is a device or meter that read frequency as an input and display its value
output device

Pen drive is an Removable Device. It is use to File sharing. Easy to Read and Write files. Pen Drive is not consider as an Input/Output Device.
An SD card is considered a storage device rather than an input or output device. It is used to store data such as photos, videos, and documents. When data is written to an SD card from a computer or camera, it is considered an output action, and when data is read from an SD card into a device, it is considered an input action.
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.
Technically speaking it is both. It can read as well write information.
Since you can both read from (input) and write to (output) a hard disk, it is considered both an input and an output device.
