About these units

The kilobyte scale covered early personal computer files in the 1970s and 1980s — text documents, simple programs, and early game files. With modern compression and media, kilobytes now describe small images and text.
Megabyte
The megabyte scale became dominant with the introduction of graphical user interfaces, color photography, and CD-ROMs in the late 1980s and 1990s.
