Serial data transfer is when we transfer data one bit at a time, one right after the other. Information is passed back & forth between the computer and Arduino by, essentially, setting a pin high or low. Just like we used that technique to turn an LED on and off, we can also send data. One side sets the pin and the other reads it.
