DLLs execute in the memory space of the calling process and with the same access permissions which means there is little overhead in their use but also that there is no The ordinal represents the position of the function's address pointer in the DLL Export Address table.
The delay-loading mechanism also provides notification hooks, allowing the application to perform additional processing or error handling when the DLL is loaded and/or any DLL function is called.
