Answer:
The answer to this question is given below in the explanation section
Explanation:
A DLL (Dynamic Link Library ) file is a compiled library that contains a set of procedures and/or drivers that are referenced and executed by a Windows program. It allows multiple programs to access shared functions through common libraries. DLL file has .dll extension at the end of file name.
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. These files can be used in more than one program and in multiple programs at the same time. Some .dll files come with windows operating system while others are added as a new program is installed on system.
