Stands for 'Dynamic Link Library'. This is an external piece of software that other applications can 'hook' into in order to make use of the functions it contains.

For example in Windows, there is a DLL that controls printing. Someone creating a Windows application that needs a print function does not have to re-invent the wheel - they simply hook into the Printing DLL that is already available as part of the operating system.
