dynamic function loading
(dī-nam´ik funk´sh&n lōd´ing) (n.) Also known as lazy loading, the capability to specify which components of a program are called into memory and which components are not called into memory by default when a program is first launched. Dynamic function loading is a method of speeding up the initial load time of a program. Because expansive applications often contain many features that may never be used, this method of loading instructs the system loader to load only the dependent components of a program that are specifically requested. In this way the performance of a program can be improved.
