Which of the following is a non-volatile storage medium?

• A. RAM
• B. Cache memory
• C. SSD (Solid State Drive)
• D. CPU registers

Answer: (C)

The selection of SSD (Solid State Drive) as a non-volatile storage medium is accurate because non-volatile storage is characterized by its ability to retain data even when power is turned off. SSDs store data on flash memory, which ensures that the information remains intact without a continuous power supply, making them an ideal choice for long-term data storage. In contrast, RAM (Random Access Memory) is a type of volatile memory that requires power to maintain the information stored within it; once the power is lost, all data is cleared. Similarly, cache memory, which is a smaller, faster type of volatile memory located closer to the CPU, also loses its contents when power is turned off. CPU registers, essential for processing data and instructions, likewise are volatile and do not retain their data without power. Thus, the SSD stands out as the only option among the choices that can preserve data under power-off conditions, reinforcing its classification as a non-volatile storage medium.
