DLL stands for Dynamic Link Library. A DLL is a special type of executable file, which can only be called from within another program. DLL’s are often produced to modularise programs, for example within GMS DLLs are used extensively where the functions within those DLLs are shared by more than one process. An example of this is the User Manager "ntmuser.dll" which is accessed by all of the GMS services.
On Unix platforms DLL’s are normally referred to as Libraries.
