It is notable that each metal strip has five clips. That means each metal strip form a half row (column A to E or column F to J) and it is electrically connected. For example, A1 is only connected to B1, C1, D1, E1 it is not connected to A2, because the hole is separate from another clip.
Similarly, it is not connected with F1, G1, H1, I1, J1 because they are on another half row of 1 and it is also divided by a gap in the middle of the breadboard.
Power rails on the opposite side of the breadboard are not connected to each other. But you can connect the power line with the jumper wires and make power and ground available on both sides.
