Historically, all library linking was static, but today dynamic linking is an alternative and entails inherent trade-offs.. An advantage of static over dynamic is that the application is guaranteed to have the library routines it requires available at run-time, as the code to those routines is embedded in the executable file.
Dynamic linking offers three advantages: Often-used libraries (for example the standard system library) need to be stored in only one location, not duplicated in every single binary. If a library is upgraded or replaced, all programs using it dynamically will immediately benefit from the corrections. Static builds would have to be re-linked first.
Some global variables (e.g. arrays of string literals, virtual function tables) are expected to contain an address of an object in data section respectively in code section of the dynamic library; therefore, the stored address in the global variable must be updated to reflect the address where the DLL was loaded to.
A program that is configured to use a library can use either static-linking or dynamic-linking.Historically, libraries could only be static. [4] For static-linking (), the library is effectively embedded into the programs executable file, while for dynamic-linking the library can be loaded at runtime from a shared location, such as system files.

In computing, a library is a collection of resources that is leveraged during software development to implement a computer program. Commonly, a library consists of executable code such as compiled functions and classes, or a library can be a collection of source code. A resource library may contain data such as images and text.
In computing, static dispatch is a form of polymorphism fully resolved during compile time. It is a form of method dispatch, which describes how a language or environment will select which implementation of a method or function to use.
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.
