Shared libraries often are called as shared objects. On most UNIX systems they are denoted with a . so suffix and Microsoft refer to them as DLLs (dynamic link libraries).

Shared libraries (also called dynamic libraries) are linked into the program in two stages . First, during compile time, the linker verifies that all the symbols (again, functions, variables and the like) required by the program, are either linked into the program, or in one of its shared libraries.
