In our increasingly connected digital world, data communication is the vital ingredient that connects us. Understanding how different methods for data transmission work is crucial to creating reliable and efficient networks. From the one-way simplicity of simplex communication to the bidirectional nature of full-duplex communication various methods determine how data is transferred and received.

To efficiently transfer data the hardware of a data communication circuit can use a variety techniques, including multiplexing as well as demultiplexing processes, which combine and separate signals into composite ones for transmission and then back into the individual components. This maximizes bandwidth utilization and lowers costs. Error-detection code and signal amplifiers can also limit the possibility of data corruption caused by electromagnetic disturbances or other noise that can alter bits of data when they travel through an electronic communication channel.

Data communications also have the following set (protocol) of rules that are followed by both the computers of the sender as well as the receiver. These rules help ensure that the message is understood and accepted without error.

The sender is the computer or device that creates and sends out the message, which may be in the form of text, numbers images, sound or video. The receiver is the computer or device that receives the message, which could be the same as the sender or different. The transmission medium is a physical path that connects the sender and receiver. It can be wired, such as fiber optic cable, or wireless like radio waves or lasers.
