Examples of 16-bit technologies include some computers and devices of the 1970s, as well as a line of Motorola processors built with 16-bit standards. Another good example is the slate of 16-bit video game consoles developed in the 1990s, including Neo Geo, Sega Genesis and Super NES.
To understand the technical capability of a 16-bit model, one may take a look at the video games played on 16-bit consoles to see the graphics and audio/video limitations of a 16-bit technology. Although limited compared to modern standards, 16-bit technology offered significant advancements over the previous generation of 8-bit technology.
