Data Communications Concepts
This section deals with the fundamental communications concepts that are key to understanding why healthcare networks are built the way they are and how they work.
Connectivity: The Geometrical Nature of Networks
Data networks make it possible for people or machines to communicate with each other, and these networks do it in the most efficient way possible. This efficiency is achieved by using technology and by making intelligent trade-offs.
Figure 35-1 shows how the number of connections increases as the number of endpoints of a network grows. The relationship is geometric (~n2/2). What this tells you is that it takes a lot of connections to make sure that many people or things can talk to each other in a network. ...
