A. B. C. D. E. F.AC.
The storage devices that have a spinning disk are:
C. HDD (Hard Disk Drive) HDDs use magnetic disks to store and retrieve digital information. These disks spin at high speeds and the data is read by a head that moves across the surface of the disk. The term "hard" refers to the rigid nature of the disks, as opposed to floppy disks which are flexible.
A. Optical drive An optical drive is a device that uses laser technology to read and write data to optical discs, such as CDs, DVDs, and Blu-ray discs. The disc spins at high speeds to enable the reading or writing of data.
The other options are:
B. SSD (Solid State Drive) An SSD stores data using NAND-based flash memory chips. There are no moving parts in an SSD, unlike an HDD. It provides faster access to data, lower power consumption, and is more reliable than HDDs.
D. Flash drive A flash drive is a small, portable storage device that uses NAND-based flash memory to store data. It does not have any spinning disks.
E. RAM (Random Access Memory) RAM is a volatile form of memory used in computers. It is used for temporarily storing data that the computer is currently using. It is not a storage device that retains data after the computer is turned off.
F. ROM (Read-Only Memory) ROM is a type of memory used to store permanent instructions that the computer uses during boot-up. It is not a storage device that can be used to store user data.
