Serial communication: Working with Arduino boards necessitates the use of serial communication and debugging. Simply put, serial communication is a method for the board to communicate with other devices, such as another computer, a peripheral, and so on. When discussing Arduino serial communication, it's also important to distinguish between its physical components (such as the Arduino's serial ports) and its software components (using the serial monitor in the Arduino IDE).
Thus serial communication helps in communicating with the devices attached to the board
