Microfloppy was a term used to describe a type of floppy disk that was developed by Sony in the 1980s. However, throughout the years, this term has become obsolete, and newer technology has emerged. Today, the commonly used term for this type of disk is floppy diskette, floppy disk, or simply diskette. Other synonyms include 3.5-inch diskette, disk, and floppy. In some cases, older disks may still be referred to as microfloppies, but this terminology is now outdated and most people will not recognize it. Regardless of the name, these disks were a crucial part of early computing and their impact on technology should not be forgotten.
