In our increasingly interconnected digital world data communication is the lifeblood that connects us. Understanding how various modes of data transmission function is essential to creating reliable and efficient networks. Different methods determine how data is transferred.

Hardware in a data communication circuit employs a variety of techniques to transmit data efficiently. These include desmultiplexing and multiplexing. These are processes that combine or separate signals and then transmit them as a single composite signal. This increases bandwidth and reduces costs. Error detecting code and signal amplifiers reduce data corruption from electric disturbances, or even momentary electrical noises that may change bits of data as they travel over the channel of communication.

Data communications also have an array (protocol) of rules which are followed by the computers used by the sender and the receiver. These rules ensure that the message will be properly understood and accepted.

The sender can be a device such as a computer or device that creates the message and then transmits it. It may be in the form text, numbers, pictures, sounds or videos. The receiver is the device or computer which receives the message which may be the same as the sender, or different. The transmission medium is the physical pathway from the sender to the receiver. It could be a wired medium such as twisted pair wire or fiber optic cable, or wireless like lasers, microwaves, or radio waves.
