USB cable wiring system

Data cables typically contain four wires (positive, negative, data transfer & data receive). The positive (+) and negative (-) wires carry electric power to the device while the other two data transfer (D+) and data receive (D-) wires are responsible for data exchange. Charge-only cables, on the other hand, only have the positive and negative power wires but lack the data exchange wires.

This configuration makes transferring of data easier and reliable. If it contains only two wires "red & black" then it is basically used for charging or powering only.
