A system* is an interconnected set of elements that is coherently organized in a way that achieves something. If you look at that definition closely for a minute, you can see that a system must consist of three kinds of things: elements, interconnections, and a function or purpose.

The second definition I will allow is a plural one: technology as an assemblage of practices and components.

I will also allow a third meaning. This is technology as the entire collection of devices and engineering practices available to a culture.
