about the main output of the (La)TeX compilation process. Not meant to be used for questions about {compiling} in general or the {output-routine}.
(La)TeX has various forms of output: the visible/printable main output file, auxiliary files, e.g. .aux, .toc, .bbl, .log etc. and terminal output. For the last mentioned there is the specific {terminal-output} tag. Questions about the afore mentioned may have the {output} tag in combination with the {auxiliary-files} tag.
There are several drivers that create output, the main ones beeing dvips and pdftex and there is a distinct {output-driver} tag that also might be used combined with the {output} tag.
In every TeX format the output is prepared with the \output macro. The {output} tag, anyways, does not correspond to the eponymous \output macro. For questions specifically about the output-routine use the according {output-routine} tag.
General questions about the process of compiling are tagged with the {compiling} tag.
