The Free On-line Dictionary of Computing (30 December 2018):
Systems or components, possibly from different
origins, working together to perform some task. Interworking
depends crucially on standards to define the interfaces
between the components. The term implies that there is some
difference between the components which, in the absence of
common standards, would make it unlikely that they could be
used together. For example, software from different
companies, running on different hardware and operating
systems can interwork via standard network protocols.
