 ## Terminal strips
 
-The holes in the middle portion. They are connected in groups of five and
-comprise two groups separated by the ditch. The terminal strips are not
-connected accross the ditch thus each of the two strips are electrically
-separate.

+## Bus strips
+
+The contact holes on the outer edges of the breadboard, designated by numbers
+(1-30). The chief role of the bus strips is to manage the power to the circuit.
+You will typically use the positive bus strip on one side for the voltage source
+and the negative bus strip on the other side for the ground outlet.
