(n ) The distance across a graph, measured by the number of links traversed Diameter is usually taken to mean maximum diameter (ie the greatest internode distance in the graph, but it can also mean the average of all internode distances Diameter is sometimes used as a measure of the goodness of a topology

segment formed form two points on the circumference containing the centre of the circle
and terminated by the opposite boundaries; a straight line which bisects a system of parallel chords drawn in a curve
the length of a line segment that starts and ends on a circle and goes through its center -- " length of a diameter is exactly equal to two times the length of a radius " (245)
