What is write protection and how does it work?

Write protection is a security feature designed to prevent unauthorized changes or modifications to data stored on a device or medium. It works by locking the device or medium, making it read-only, and preventing any new data from being written to it. This feature is commonly used on USB drives, SD cards, and other portable storage devices to safeguard sensitive information from being altered or deleted.

When a device or medium is write-protected, any attempts to modify or delete existing data will be blocked. This ensures that the data remains intact and unchanged, even if the device falls into the wrong hands. Write protection can be implemented through hardware or software means, depending on the device or medium being used. For example, some USB drives have a physical switch that can be flipped to enable or disable write protection, while others may use software-based solutions to achieve the same effect.
