The breadboard is organized as rows and columns of interconnected contact points. The top and bottom rows are typically connected horizontally across the whole length of the board and used to distribute power to the individual circuit elements. The remaining contact points are connected vertically, usually in groups of 5. The picture below shows a breadboard (click to enlarge) that has two horizontal rows at the top and two at the bottom. In between are two sets of columns, each of which consists of 5 contacts.
