Which of the following statements about write protection is true?

Write protection is a mechanism that prevents data from being modified or overwritten, thereby preserving the integrity of the information stored. The correct statement indicates that write protection can employ both hardware and software methods.

Hardware write protection may involve physical switches or write-protect tabs that block writing to storage media. For example, some USB drives and other removable media have physical locks that prevent data from being written. On the other hand, software write protection involves using operating system settings or file attributes to restrict write access to files or directories, such as setting files to "read-only." This dual approach allows for flexible and effective protection against unintentional modifications or deletions.

Understanding this concept is important, as it highlights the various strategies organizations can use to safeguard sensitive data from unauthorized changes or accidental deletion, thereby maintaining data integrity and security.
