What is unique about non-volatile memory?

Non-volatile memory is characterized by its ability to retain stored information even when the power supply to the computer is turned off. This feature is crucial because it allows users to preserve data without needing continuous power, making it ideal for long-term storage solutions such as SSDs, flash drives, and ROM.

In contrast, volatile memory, such as RAM, loses all stored data when the power is removed, necessitating a constant power supply to retain information. This distinction is foundational to understanding how different types of memory function and their respective use cases within computing systems. Non-volatile memory's unique property is what enables devices to store essential data, like operating systems, applications, and user files, securely and reliably over time.
