Let's say you have three source code files, foo.cpp, bar.cpp and baz.cpp.

Here are the three translation units, which translate from the source file
to the object file.

g++ -c foo.cpp -o foo.o
g++ -c bar.cpp -o bar.o
g++ -c baz.cpp -o baz.o


When linking the object files together, that process is not a translation
unit.

g++ foo.o bar.o baz.o -o quux

HTH,
