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.

A large system (like the Internet or a corporation) can have many interfacing subsystems.
