Definition: A state where data storage devices allow data to be read but prevent any modifications or writing.
Explanation
Read-only mode is a security and data integrity feature that restricts storage devices or files from being altered. When enabled, users can access and copy data but cannot modify, delete, or add new data. This mode is often enforced through hardware switches, firmware controls, or software settings to protect against accidental or malicious data changes.
Example
A USB flash drive with a physical write-protect switch set to read-only mode prevents users from accidentally deleting or modifying files, ensuring the stored data remains intact during transport or sharing.
Who This Is For
This mode is essential for IT professionals, healthcare and government sectors, industrial operations, and anyone needing to maintain strict data integrity and prevent unauthorized changes to critical information.
