Asked in Floppy Disk Drives
Is the Floppy disk an input device or output device?
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.

If the hard drive did not have the capability of input and output, it would not be useful in its application in the computer.
