A build just compiles only the source files that need to be compiled & links them together to form a new binary.

A clean build deletes all binaries and recompiles all the source files again from scratch & further links them together to form a new binary.

Typically, to save time in re-compilation a utility called Makefiles is used, In the Makefiles you are allowed specify dependencies for source files which formulate the rules for compilation in case any some of the source files are modified. The first case only compiles and links the source files that need to be compiled as per rules in the Makefile.
