On Nikon and some other cameras, image files often start with names like DSC_1234 or _DSC1234. What does the "DSC" prefix mean, and why is it used instead of something else?

CIPA (the Camera & Imaging Products Association) has long established DSC as meaning Digital Still Camera. This prefix is not mandated by the DCF (Digital Camera Filesystem) standard but was adopted uniformly by Nikon and Fuji which named their files starting with DSC_, DSCN, or DSCF. Other manufactures went with PICT, PIC or P which presumable all stand for Picture. Although plenty of cameras also save videos with the same convention.
You will notice that DCF requires files in AdobeRBG color-space to start with an underscore, in which case DSC is often all that is left and you get _DSCxxxx.yyy uniformly for Nikon and Fuji.
As ahockley pointed-out, Sony coincidentally uses the DSC prefix for fixed-lens camera names as well.

"DSC" commonly stands for "Digital Still Camera." It became a widely adopted filename prefix used by brands such as Nikon and Fuji, even though the DCF (Digital Camera Filesystem) standard does not require that exact prefix.
Different manufacturers chose different naming conventions: some used "DSC," while others used prefixes like "PICT," "PIC," or just "P," likely meaning "Picture." So the prefix is mostly a manufacturer convention rather than a technical requirement.
One related DCF convention is that files tagged as Adobe RGB often begin with an underscore, which is why Nikon/Fuji filenames may appear as "_DSC1234" instead of "DSC_1234."
Sony also uses "DSC" in some product names, where it likewise means "Digital Still Camera."
