What is a Dynamic Link Library (DLL)?

A DLL is a file format utilized by Windows to house shared functions, procedures, and resources. Examples of what a DLL might contain include:

• Shared logic or functions used by multiple programs.
• UI elements like icons and buttons.
• System-level processes, such as file input/output operations or memory management.

Unlike executable (.exe) files, DLLs are not standalone programs. They rely on another program or process to activate their functions.
