No, it is a mass storage device.
no
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.
A output device is what you plug into a computer, such as mouse, keyboard, external hard drive, USB etc.
Computer
A hard disk drive (HDD) is neither an input nor an output device. It is a Storage Device. It helps to store the data in a Non-Volatile form (i.e Data stored in Hard Drive is not lost even after it's power source removed) and data can be retrieved at any time by enabling power for the Hard Drive.
It is. However, it is also an output drive. Since you can store information on a hard drive, as well as reading information from it, it is both.
Neither. Is Your hard drive input or output? Neither. It is simply a storage device as a flash drive or internal optical drive would be.
A CDROM drive is neither an input device or an output device. A CDROM drive is a storage device.
It's an input and an output device. Programs and data are input from the hard-drive to the computer's memory for processing. The results are written back onto the drive when you save your work.
storage devices like the hard drive
A CPU is a central processing unit. It is neither an input nor an output device, but it is usually connected to both kinds of devices. An input device would be a keyboard or a mouse. And output device would be a printer, a hard or floppy drive, or a memory chip in a thumb drive.
no. it is a backing storage device. because it gives the user fast access to the information held on them.
