Object module
An object module is a compiled, executable program which is either a set of routines to be called from another program (such as a .so file on Linux systems or a .DLL file under Microsoft Windows) or is a compiled program not designed to be run separately which will become part of another program, such as the source code of a Pascal unit, a .OBJ file under Microsoft Windows and MS-DOS, or a .O file in Linux.
