Which of the following best describes a solid-state drive (SSD)?

• A. It is primarily used for internet browsing
• B. It has spinning disks for data storage
• C. It is a non-volatile storage device without moving parts
• D. It is slower than a hard disk drive (HDD)

Answer: (C)

A solid-state drive (SSD) is a non-volatile storage device, which means it retains data even when power is turned off. Unlike traditional hard disk drives (HDDs), SSDs do not have moving parts; they use flash memory to store data. This lack of mechanical components contributes to several advantages, including faster data access speeds, reduced latency, and greater resistance to physical shock. SSDs are particularly valued for their performance improvements over HDDs, especially in tasks that require quick read and write speeds.

The other options present different characteristics not applicable to SSDs. For instance, while SSDs can be used for internet browsing, they serve a much broader purpose than just that. Additionally, SSDs do not utilize spinning disks; that feature is characteristic of HDDs, where data is written and read from magnetic platters. Regarding speed, SSDs are generally faster than HDDs, which contradicts the claim that they are slower. Understanding these distinctions highlights the unique attributes of SSDs in the context of data storage technology.
