Networks

This is pretty straight forward stuff. Nothing especially technical. We are concerned with the big picture related how systems integrate into organisations and how people use them. I used the standards from the IB, but added some other topics I think fit into this category (but not included by the IB).

The big ideas in system fundamentals

Systems in Organizations

A computer program or computer system is used by people who work in organizations. It is very helpful to understand how people, computers, and organizations work together.
