Why is the storage capacity of a hard disk greater than a floppy disk or DVD usually?

Hard disks use advanced magnetic storage technology with multiple platters, allowing them to store significantly more data than floppy disks or DVDs, which have limited physical space for data storage.

The storage capacity of a hard disk is greater because it uses more advanced technology, such as higher-density platters and faster data access, compared to floppy disks or DVDs. Hard disks have multiple layers of storage, while floppy disks and DVDs have limited physical space and less efficient data encoding.
