The correct option is A. are volatile. Explanation of the Correct Answer Volatility in Storage Media: - Volatile storage refers to memory that requires power to maintain the stored information. When the power is turned off, the data is lost. Examples of volatile storage include RAM (Random Access Memory). - Secondary storage media, on the other hand, are designed to retain data even when the power is turned off. This characteristic makes them non-volatile. Types of Secondary Storage: - Common examples of secondary storage include hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, and optical discs (like CDs and DVDs). All of these retain data without needing a constant power supply. Why the Other Options are Correct B. are non-volatile: - This statement is true. As mentioned, secondary storage retains data without power, making it non-volatile. This is a fundamental characteristic that differentiates it from primary storage (like RAM). C. are relatively cheap: - This statement is also true. Secondary storage media, especially HDDs and USB drives, are generally inexpensive compared to primary storage options. The cost per gigabyte for secondary storage has decreased significantly over the years, making it an economical choice for data storage. D. have storage capacity: - This statement is true as well. Secondary storage media are designed to hold large amounts of data. For instance, modern HDDs can store several terabytes of data, and SSDs are also available in high capacities. This is one of the primary reasons they are used for data storage in computers and other devices. Summary of Key Points

• Volatile vs. Non-volatile: Secondary storage is non-volatile, meaning it retains data without power, unlike volatile memory (e.g., RAM).
• Cost-Effectiveness: Secondary storage is relatively cheap, making it accessible for large data storage needs.
• High Capacity: Secondary storage media are designed to have significant storage capacities, suitable for various applications.

Common Pitfalls to Avoid

• Confusing volatile and non-volatile storage: Remember that volatile storage loses data when power is off, while non-volatile storage retains data.
• Overlooking the cost aspect: While secondary storage is generally cheaper, prices can vary based on technology (HDD vs. SSD) and capacity.
• Assuming all storage media have the same capacity: Different types of secondary storage have varying capacities, so it's essential to choose the right one based on your needs.

By understanding these concepts, you can better appreciate the role of secondary storage in computer systems and make informed decisions regarding data storage solutions.
