Models and maps reveal the structure, connections and patterns within a digital system. They can show how data, people, devices, organizations and processes interact, but they do not reproduce the whole system or provide a completely neutral view of it.
In IB Digital Society, this question tests the systems concept, especially the idea that systems contain interacting, interdependent and interconnected elements. A model simplifies a digital system so that a particular relationship becomes easier to understand. For example, a data-flow model might show how information is collected, processed, stored and shared. A network map might reveal which devices or organizations are central, where information enters or leaves the system, and where a failure could spread.
Models and maps can therefore reveal:
- the main elements and boundaries of a system;
- relationships, dependencies and flows between elements;
- concentrations of control or access, which can expose power within the system;
- feedback loops and possible points of failure; and
- intended and unintended consequences when one element changes.
However, the misconception is that a model or map is an objective picture of reality. Every representation involves selection: its creator decides what to include, exclude, measure and emphasize. A map of internet access, for instance, may show national coverage while hiding differences between urban and rural communities or between connected and excluded people. The representation can therefore make some impacts visible while concealing others.
This is shared SL and HL content under 2.6 Systems. For an IB Explain question, state what the model or map reveals and then develop the reason: it makes relationships or patterns visible that may be difficult to identify from isolated data. In an extended response, evaluate both its usefulness and its limitations, linking the representation to specific people and communities rather than treating it as complete evidence.
