Introduction to Serial Port
What Is Serial Port in Computer?
Serial Port is a communication port in the computer which uses serial data transmission technique for the transfer of data. This means that it is a communication interface through which the data or the information can be transferred in serial transmission mode i.e. One Bit per second.

Today, The modern personal computers do not utilizes this port as it uses serial communication method, thus was very slow. Now mostly all computers uses parallel port the communication of data. As parallel port is faster than serial port. The serial port is not used in personal computers anymore but it does not mean that it is of no use at all. It is still used in some Consumer Products, In Industries and Automation Systems etc. As its manufacturing costs are very low. Thus it is very cheaper than parallel port. And most of the times there are more chances of corruption of data in parallel port as compared to the serial port. A serial port also have the advantage that it requires very little supporting software from the host system.

Applications of Serial Port:
As in modern computers, serial ports are not used anymore, but still they finds their application in Industries and Consumer products. Following are the main fields of application of Serial Port:
