What are the features of a floppy disk?

A floppy disk is a portable storage medium characterized by its thin, flexible magnetic disk encased in a square or rectangular plastic shell. Typically available in sizes such as 3.5 inches and 5.25 inches, it can store data ranging from 360 KB to 2.88 MB, depending on the format. The disk is accessed through a read/write head, and it often features a write-protect tab to prevent accidental data loss. Despite being largely obsolete today, floppy disks were integral for data transfer and storage in the late 20th century.
