Question: Which of the following helps to protect floppy disks from data getting accidentally erased?

Answer:

The write-protect notch or tab helps to protect floppy disks from data getting accidentally erased.

Floppy disks, which were commonly used for data storage in the past, often had a small notch or tab on the side. This notch or tab could be moved to a specific position to enable or disable the write-protection feature of the floppy disk.

When the write-protect notch or tab is in the "write-protect" position, it prevents any data from being written, modified, or erased on the floppy disk. This physical mechanism acts as a safeguard to protect the data on the floppy disk from accidental deletion or overwriting.

By moving the write-protect notch or tab to the appropriate position, users can prevent data loss by ensuring that the floppy disk is read-only and cannot be modified. This feature was particularly useful when users wanted to protect important data on a floppy disk from being accidentally altered.

It's important to note that floppy disks have become less common and have been largely replaced by more advanced storage technologies such as USB flash drives and cloud storage. However, the write-protect mechanism was a notable feature of floppy disks in their time.
