Serial Vs Parallel. In a series circuit the current that flows through each of the components is the same and the voltage across the circuit is the sum of the individual voltage drops across each component. In serial processing data transfers in bit by bit form while in parallel processing data transfers in byte form i e.
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. Computers have a variety of input and output devices. A serial port can also be referred to as a communication port or bi directional port.
However though the data is transmitted bit by bit serial communication is fast for long distances and high frequencies.
A serial port can also be referred to as a communication port or bi directional port. 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. Thus a parallel port transmits data much faster than a serial port. As against in parallel communication multiple parallel links are used that transmits each bit of data simultaneously.
