Answer Posted / Guddu Kumar
"Dynamic loading," "dynamic linking," and "overlays" are techniques used by operating systems to manage program memory efficiently. 1) Dynamic loading is a method where an executable program does not include all of its required libraries or modules at load time, but instead loads them on-demand as needed; 2) Dynamic linking is similar to dynamic loading, but the linking occurs when the program is run, allowing shared libraries to be used by multiple programs simultaneously; 3) Overlays are separate parts of a program that can be loaded and unloaded from memory as needed to conserve resources.
