A .lib is a static library that gets linked to your code.
A .dll is a dynamic library that gets loaded by your code at runtime.
Both provide a way for you to combine large portions of shared codebase into one file.


With a .lib, this means project A doesn't need to compile all the .cpp files that were put into the .lib, it just uses the .h files and links against the .lib. This is a good way to store shared code between projects (sound API, network API, graphics API, windows even has .libs you link against)

With a .dll, everything is linked at runtime, so you can update / change the dll to change functionality. This is good for things like plugins for photoshop or maya for example, where the system expects a dll with some set of functions in it, and if it gets that it can just link and call those functions.
