Share this item with your network: Modern serial ports are used in scientific instruments, shop till systems such as cash registers and applications like industrial machinery systems. Before establishing the communication, the sender and receiver must agree on the signaling parameters.
As a comparison, parallel ports transfer all the 8 bits of a byte in parallel, all in one go, over a cable with 8 wires.
However, if you are a lucky owner of an up-to-date computer, to find a serial interface will be a bit harder. The same cannot be said about industrial equipment though. Hence, a parallel port transmits data faster while a serial port is used for communications with relatively slow data rates.
Conventional computers and their programs operate in a serial manner, with the computer reading a program and performing its instructions one after the other. This new technology could transfer data at high rates on the same bus, called a daisy chain.
Serial buses[ edit ] Many communication systems were generally designed to connect two integrated circuits on the same printed circuit boardconnected by signal traces on that board rather than external cables. A vast number of current industrial instruments still use COM ports as the main method of connection to a computer.
What is serial communication interface? Serial communication is a communication established via serial interfaces which transmit data over one wire one bit at a time. In many cases, serial is cheaper to implement than parallel.
On your PC, the printer is usually attached through a parallel interface and cable so that it will print faster. Integrated circuits are more expensive when they have more pins. Practically all long-distance communication transmits data one bit at a time, rather than in parallel, because it reduces the cost of the cable.
Today, the serial port is seldom used but can be found as a communication device for GPS receivers, LED and LCD text displays, bar-code scanners and flat-screen monitors. A parallel link transmits several streams of data simultaneously along multiple channels e. Several factors allow serial to be clocked at a higher rate: Bi-directional communication As you may have heard, serial ports are bi-directional interfaces.
To start the data exchange, a serial port sends a start bit a single bit with a value of 0. Because many of the pins were unused and were quite bulky, the smaller DE-9 connector became popular. Originally, the standard used 25 pins.
It is one of the oldest types of interfaces and at one time was commonly used to connect printers and external modems to a PC.
Compared to a parallel port, the data transfer rate of a serial port is slower. Serial port programming What is meant by serial communication? Higher speed communication was needed for serial communication, such as external data storage units.
To reduce the number of pins in a package, many ICs use a serial bus to transfer data when speed is not important. Crosstalk is less of an issue, because there are fewer conductors in proximity. Many ICs have serial interfaces, as opposed to parallel ones, so that they have fewer pins and are therefore less expensive.
A serial port is an interface that allows a PC to transmit or receive data one bit at a time. The serial port uses a nine-pin DE-9 connector or a pin DB connector.What is meant by serial communication? Serial communication is a communication established via serial interfaces which transmit data over one wire one bit at a time.
