Serial Vs Parallel. Parallel transmission is faster than serial transmission to transmit the bits. In serial processing data transfers in bit by bit form while in parallel processing data transfers in byte form i e.
A circuit composed solely of components connected in series is known as a series circuit. The key difference between serial and parallel communication is that in serial communication data transmission occurs bit by bit at a time while in parallel communication multiple bits transmit at a time. Thus a parallel port transmits data much faster than a serial port.
The example of parallel communications are computer to printer and communication between internal components in embedded systems the parallel communication provides quick and high speed transmission but at high cost and requires more wires.
In serial processing same tasks are completed at the same time but in parallel processing completion time may vary. 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. The example of parallel communications are computer to printer and communication between internal components in embedded systems the parallel communication provides quick and high speed transmission but at high cost and requires more wires. One key difference between a serial and parallel port is that the serial port allows for data to be transferred to the hard drive from a remote device or transferred from the hard drive to a remote device as opposed to the parallel port s outbound only communication.
