Nonvolatile memory is best described as storage that retains data without power. This type of memory is fundamentally different from volatile memory, which loses its contents when power is removed. Nonvolatile memory is crucial for preserving data over time, even when the device is turned off. Examples of nonvolatile memory include flash memory, ROM, and hard drives, which allow users to save files and access them later without needing a constant power source.

The other choices pertain to different types of memory or storage characteristics. Volatile memory, such as RAM, loses its data when the system is powered down, and is better associated with temporary storage for active computations. The main working memory of a computer (often referred to as RAM) is designed to enhance performance by providing fast access to the data and instructions needed for executing programs, but it is also volatile. Therefore, knowing the specific function and behavior of nonvolatile memory helps in distinguishing it clearly from the other types of memory mentioned.
