floppy disk
A floppy disk is a data storage medium that was widely used from the 1970s to the early 2000s. It consists of a thin, flexible magnetic disk enclosed in a square or rectangular plastic shell. Floppy disks were commonly used to store and transfer files between computers, especially before the advent of more advanced storage solutions like USB drives and cloud storage.
Floppy disks came in various sizes, with the most popular being the 3.5-inch disk, which could hold 1.44 megabytes of data. They were inserted into a floppy disk drive on a computer, allowing users to read and write data. Although largely obsolete today, floppy disks played a significant role in the early days of personal computing.
