No. A disk drive can use one of several methods of storing data, including magnetic, Flash, and optical.
no,harddisk is not an optical storage
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.
It is a compact disk. Or it could be anything under optical disk drive.
An Optical Disk
A Optical drive is hardware that read and drive a DVD disk or programs.
optical disk storage are read only so they cannot get infected. But if you burn files which are infected by viruses then the optical disks can spread the virus
The disk drive
(a)- it is a read-only storage medium. Data once recorded, cannot be erased, and hence the optical disk cannot be reused. (b)- thd data access speed for optical disk is slower than magnetic disks; (c)- optical disk require a more complicated drive mechanism that magnetic disk.
Optical disk
yes
Hard disk drive is a storage device.its is a non-volatile storage device
DVD and RAM are not permanent storage devices.
