Static libraries are linked during compilation and their functions are built into the executable file, increasing its size, while dynamic libraries are linked during execution by the operating system and loaded only once into memory from multiple programs, making programs smaller and faster to execute but potentially less compatible if the library is removed or updated.

1. Properties Static libraries Dynamic libraries
Linking time In the last step of compilation
process
During linking process when
executable file and libraries are
added to memory.
Performer Linker Operating system
Memory Increase the size of the program
because the static libraries
functions are built in the
executable file.
Smaller, because multiple
programs call the library, only one
instance of the shared library is
needed in memory.
Updates If are changes on libraries, the
executable file must be
recompiled.
If changes in libraries, don´t need
to recompile.
Time The executable files is loaded Ton
memory every time is executed,
meaning more time to execute.
Are faster because the library is
already in the memory.
Compatibility issues Not possible, due to all the code is
in a unique file.
Depends on have a compatible
library. If the library is removed,
the program wouldn't work.
