Question
What type of storage device uses magnetic disks to store data?
a. SSD
b. HDD
c. RAM
d. ROM
Solution
The type of storage device that uses magnetic disks to store data is b. HDD (Hard Disk Drive).
Explanation:
- HDD: Hard Disk Drives store data on rotating magnetic disks (platters). These disks are read by a magnetic head that moves across the surface to access the data.
- SSD: Solid State Drives do not use magnetic disks; they store data on flash memory chips.
- RAM: Random Access Memory is a type of volatile memory used for temporary data storage while a computer is running, not magnetic disks.
- ROM: Read-Only Memory is a type of non-volatile memory used to store firmware, not magnetic disks.
Thus, the correct answer is HDD.
