The carputer frontend, like any frontend, is the part of a software system which allows the user to interact with the computer and any application software which it is running. Not surprisingly, the term backend is also used and this denotes the part of the software which does the processing in the background. Individual programs or software suites can themselves have Frontends and Backends. However in our context of car PC's, we tend to use carputer frontend to mean a discrete program, which may have inbuilt functionality of its own, but which has as its main function, the role of controlling and passing data to other stand-alone applications.
