The correct answer is: D. All of the above
A floppy disk is a portable, magnetic storage medium that was widely used for data storage and exchange from the 1970s to the early 2000s. Floppy disks were typically 3.5 inches in diameter and could store up to 1.44 megabytes of data.
Floppy disks could be protected from being written to or read by using a write-protect tab. This tab was located on the edge of the floppy disk and could be flipped up or down to enable or disable write protection.
When the write-protect tab was flipped up, the floppy disk could not be written to. This was useful for preventing accidental data loss or for protecting sensitive data.
When the write-protect tab was flipped down, the floppy disk could be written to. This was necessary for saving data to the floppy disk.
Floppy disks are no longer widely used, but they may still be used in some older computers or devices.
