Tomorrow’s Technology and You 8/e Chapter 12 Systems and Organization
Every system has a boundary that defines its limits.
The environment is anything outside the system’s boundary.
A system can be a part, or a subsystem, of a larger system.
For example, a personal computer can be a subsystem of a LAN, which might be a subsystem of a WAN, which could be a subsystem of the Internet.
An Interface is a shared boundary between systems.
When the output of one subsystem is used as the input for another subsystem, they are interfacing.
