To determine which of the options is NOT a long-term storage device, we first need to clarify the function and characteristics of each option:

1. Hard Disk: A hard disk drive (HDD) is a traditional storage device that uses spinning disks to read and write data. It is considered a long-term storage device as it retains data even when the power is off.

2. Flash Drive: A flash drive is a portable storage device that uses flash memory to store data. Like hard disks, flash drives are long-term storage solutions because they do not lose data when powered off.

3. RAM (Random Access Memory): RAM is a type of computer memory that is used to store data and machine code currently being used. It is volatile memory, meaning that it loses its contents when the power is turned off and is therefore NOT a long-term storage device.

4. Compact Disc (CD): A CD is an optical disc used for storing data. It retains information without power and is categorized as a long-term storage device.

Conclusion:

The option that is NOT a long-term storage device is RAM.
