ROM is permanent storage because you can not alter data in ROM
A CD-ROM (Compact Disc Read-Only Memory) is considered a permanent storage device. It is designed to store data that is not meant to be modified or erased, making it suitable for applications like software distribution and media storage. However, while the data on a CD-ROM is permanent, the physical medium can be susceptible to damage over time, which may affect its longevity and accessibility.
Temporary and permanent are antonyms. Temporary means for a short period of time and permanent means for a long time/forever.
