What is the difference between implicit and explicit loading of a dll?

Implicit linking – this is loads automatically at the application startup itself and loaded throughout life of program. Consuming the memory which can be made available to other applications while not in use.

Explicit – Explicitely loading dlls into memory by calling fuctions such as loadlibrary. Then user can take the fuction pointers of exported funcions calls the funcitons and afte use and unload library, freeing memmory consumed by dll , so that it can be available to other use.
