subsystem. The software and/or hardware facilities that provide users with access to a set
of communications services.
In DSM, a program or set of processes that manages a cohesive set of objects. Each
subsystem has a process through which applications can request services by issuing
commands defined by that subsystem; in some cases, this process is the entire
subsystem. Many subsystems also have interactive interfaces.
