Serial Vs Parallel Communication. 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 crucial difference between serial and parallel communication is that in serial communication a single communication link is used to transfer the data from an end to another.
Serial transmission requires a single line to communicate and transfer data whereas parallel transmission requires multiple lines. Serial transmission is used for long distance communication. Parallel transmission is used for short distance.
Parallel communication uses more wires to allow the transfer of data simultaneously.
Serial transmission requires a single line to communicate and transfer data whereas parallel transmission requires multiple lines. 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 crucial difference between serial and parallel communication is that in serial communication a single communication link is used to transfer the data from an end to another. Serial communication uses fewer connections and cables than parallel communication does.
