Advantages and Disadvantages of Using Parallel Data Transmission. The main advantages of parallel transmission over serial transmission are: it is easier to program; and data is sent faster. Although parallel transmission can transfer data faster, it requires more transmission channels than serial transmission.
Technologically advanced world. The two most basic methods of digital communication are: Serial and Parallel. Parallel communication involves multiple wires running parallel to each other and can transmit data on all the wires simultaneously. However, Serial communication requires a single wire for transferring data bits one at a time.

A natural question arises out of human curiosity: which one of the two methods is better. This term paper discusses these two methods, their various applications and the advantages of the Serial Communication method over the Parallel one. Which dramatically increases the data transfer performance giving up to 10Gbps bi-dir ectional speed 1. All of these tremendous innovations have possible because of the advancement in the data tr ansmission methods. Basically, there are two different methods of data transmission: Serial and Parallel.
Serial transmission involves a single stream of data being transmitted over a single channel whereas parallel transmission is able to transmit several streams of data along multiple channels. To achieve fastest transmission technology, it is very important to analyze the effectiveness of both the methods. At first site, it seems that the Parallel Transmission is faster because of the multiple bits transmission at a time.
The earlier communication standards were more inclined towards the Parallel Transmission Architecture but recently, there is a shift towards the Serial Techniques as latest technology and research in the Serial Transmission domain has allowed it to become even faster than the Parallel Transmission. Also, many problems in the. In this type of data transmission, the digital information is exchanged across the communication network using one wire only. Unlike parallel communication, only one data bit is sent across the link at a time. The electronics devices are able to communicate with the outside world using Serial method of Communication.
The communication media in serial transmission is mostly wire based but can be optical or radio based also. The digital information flows as a single stream of data. However, the microprocessors inside the electronic gadgets process the data in bit-parallel mode, so a transmitter is required to convert parallel data to serial form at the transmitter end, and to convert from serial to parallel at the receiver end.
The D-shaped 9-pin connection-port is a very nice example of Serial Data Transmission port. It uses two loops of wire for the communication of data. Also, there are additional wires to control the flow of information. However, in any given direction, the data still flows over a single wire. Other examples include USB, FireWire, SATA and PCI Express. A UART (Universal Asynchronous Receiver/Transmitter) is used in the serial transmission technology.
