Which term defines a memory that retains data without power?

• A. Volatile memory
• B. Non-volatile memory
• C. Dynamic memory
• D. Static memory

Answer: (B)

Non-volatile memory is the correct term for memory that retains data without power. This type of memory is designed to hold information even when the device is turned off or loses power, making it essential for storing important data long-term. Examples of non-volatile memory include ROM (Read-Only Memory), flash memory, and solid-state drives (SSDs). In contrast, volatile memory requires a constant power supply to maintain the stored information. This is typical of RAM (Random Access Memory), which loses its data when the power is turned off. Dynamic and static memory are both types of volatile memory; dynamic memory needs to be constantly refreshed to maintain the data, while static memory holds the data without refresh but still requires power. Understanding these distinctions is crucial for grasping how various types of memory function in computing devices and how they are utilized in different scenarios. Non-volatile memory plays a vital role in ensuring that data remains intact across power losses, thus providing reliability and stability in digital storage.
