PHYSICAL COMMUNICATION

The physical connection determines how many bits (1's or 0's) can be transmitted at a single instance of time. If only 1 bit of information can be transmitted over the data transmission medium at a time then it is considered a Serial Communication





If more than 1 bit of information is transmitted over the data transmission medium at a time then it is considered a Parallel Communication.
