Floppy disks are 3.5" (formerly 5.25") Magnetic Disks hidden inside of thin, plastic casing. Floppies were first introduced in 1976 by Shugart Associates. Back in the day, floppies were the main way to put programs on your computer. For example, Windows 1.01 installed off of five 360-kilobyte 5.25-inch floppy disks. Although floppies now hold 1.44 megabytes (One type even holds 2.88MB), and have been long-superceeded by other media (CD-ROMs, DVDs, Flash Media, etc.), they are still a widely used option when it comes to computers.
