Communication Networks/Parallel vs Serial. Communication Networks. (ISI) and noise, and therefore the data can be corrupted over long distances. This page covers advantages and disadvantages of Serial Interface. In serial communication data bits are transmitted one after the other in. PISO and SIPO shift registers are used to convert serial data into parallel data and vice versa. Triac JUGFET vs MOSFET IoT Wireless RF Over Fiber IP2 vs IP3 ASK FSK PSK.

Serial port communication, which uses Serial ports, was once a popular method of transmitting data. In Serial communication, at a time through a serial port, over a single communication line.

Well, if you can find that, then you are actually looking at a serial port.

Serial ports also known as COM (communications) ports were extensively used earlier. Serial communication was popular because most computers had one or more serial ports. All you needed was a cable to connect the instrument to the computer or two computers together. If you are not familiar with computer hardware terms such as ports, input output devices, modem, and so on then will give you ample knowledge on computer parts and terms.

Serial ports have been around for decades, followed by Parallel ports for transmitting data between a computer and a peripheral or serial device such as a mouse, modem, a programmable instrument, or between two computers. But with the introduction of USB, FireWire, and other faster solutions in recent times, it’s more likely that both serial and parallel ports will be soon completely replaced by the USB ports. Serial Port Details The phrase “serial” implies that a serial port “serializes” data, which means it takes a byte of data and transmits serially each of the 8 bits of a byte one at a time. This is in contrast to a Parallel Port where all the 8 bits of a byte are transmitted in parallel, all at one time, over a cable with 8 wires. So a serial port needs only one wire to transmit the 8 bits.

Serial port communication is useful when data transfer rates are low. Compared to a parallel port, the disadvantage of Serial port is that it takes 8 times longer to transmit the data, but the advantage is that cables used with a Serial port are cheaper and narrower. Serial ports are bi-directional. Bi-directional communication allows each device to receive data as well as transmit it. Serial devices use different pins to receive and transmit data.

So this makes a serial port suitable for full-duplex communication, in which information can travel in both directions at once. Before starting transmission of each byte of data, a serial port sends a start bit, which is a single bit with a value of 0. After a byte of data is transmitted, it sends a stop bit to signal that the byte transmission is complete. Pin Information of a Serial Port DB9 connector is a typical Serial Port and below is a description of the signal and signal name against each pin of the connector. Pin 1 is the one on the top left and pin 9 is in the bottom right.
