system

A system is a group of things that connect and form some kind of coherent whole. All the individual buses and the separate routes they take through your city are together called a bus system.

Any time various separate things act together in some organized way, you can call the entire group of interconnected things a system. Your veins, arteries, and heart together make up your body's circulatory system, and the group of planets which rotate around the sun are called a solar system. The Greek word systema, or "organized whole," is where system originates.
