Don’t know the actual names for the first two, but since third one is a floppy disk, they’re all computer disks.
oh god I remember when I used to think the first two were “floppy” disks and the last one was a “hard” disk
Always wondered why they were called floppy disks when they were clearly hard
Haha, yeah! (And disks, when they were clearly not round…)
(answer to both, of course, was “it’s the actual thing inside that plastic case” but I didn’t learn that for a while)
