Stands for "Dynamic Link Library." A DLL (.dll) file contains a library of functions and other information that can be accessed by a Windows program.
When a program is launched, links to the necessary .dll files are created.
If a static link is created, the .dll files will be in use as long as the program is active.
If a dynamic link is created, the .dll files will only be used when needed.
Dynamic links help programs use resources, such as memory and hard drive space, more efficiently.
