Question 3

Solid-state drives (SSD) hold non-volatile memory.

Solid-state drives (SSD) are a type of storage device that uses non-volatile memory to store data persistently, meaning the data remains intact even when the power is turned off.

A) Solid-state drives (SSD)

This option is correct because SSDs utilize flash memory, which is a form of non-volatile memory. Unlike volatile memory, which loses its data when power is lost, SSDs retain stored information, making them suitable for long-term data storage.

B) Random-access memory (RAM)

This option is incorrect as RAM is a type of volatile memory. It requires continuous power to maintain the stored information, meaning that once the power is turned off, all data in RAM is lost.

C) Read-only memory (ROM)

While ROM is a type of non-volatile memory, it is not classified as a minor component in the context of storage devices. ROM is primarily used to store firmware and is not typically categorized alongside SSDs in discussions of storage solutions.

D) Arithmetic-logic unit (ALU)

This option is incorrect because the ALU is a digital circuit used to perform arithmetic and logical operations. It does not store data and is not associated with memory storage, volatile or non-volatile.

Conclusion

The correct answer is solid-state drives (SSD) as they are specifically designed to hold non-volatile memory, ensuring data retention without power. Other options either pertain to volatile memory (RAM), do not serve as storage devices (ALU), or are not categorized in the same context as SSDs (ROM). Thus, SSDs are the clear choice for holding non-volatile memory.
