The Difference Between Parallel & Serial Communication Communication between two machines requires a transfer of signal from an output to an input. There needs to be a sender and receiver of the signal for the complete communication process to take place. Serial and parallel communications are both ways of transferring data over networks. Both systems have a unique way of operating, with differences between the two ranging from the mode of relaying signals to the level of connectivity they require. DATA TRANSFER A serial communication device transfers data in bits in the same direction. A parallel communication device sends data in multiple bits to the same direction. In serial communication a word of eight bits in length is sent sequentially, and is received after all eight bits are sent, one at a time. The bits are then assembled back into one byte which is the initial communication. In parallel communication the eight bits are transferred in corresponding 8 channels, every ch
