When used to model a system, each component within the system is represented by a block and the connections between the blocks are used to indicate that each component is properly performing its intended function. 3. If a connection exists between the two end points of the diagram, it is said that the system is performing its intended function … xref For instance, choosing the distribution that matches the data is of primary importance.
