For an entity in a system, the *(term) for being linked to other entities, that is, there being _(input) and _(output) between the entity and others, faster than the speed that the entity can stabilize.

For a system, having entities linked with each other.

In a common, restricted meaning for systems, implies that little trust exists between the entities, and/or that the system is organized in a centralized way, and programmers only having access to very low-level communication primitives, and having to hand-design the way _(information) is organized in the system (which is also a form of _(centralization), as a one brain decides for all the system).
