Data communication is essential to our ever-growing digital world. Understanding how various modes of data transmission work is vital for designing reliable and efficient networks. Different methods determine the way data is transmitted.

To transfer data efficiently the hardware of a data communication circuit uses a variety of techniques, including multiplexing as well as demultiplexing processes, which combine and separate signals into single composite ones for transmission, and then back into the individual components. This increases bandwidth and lowers costs. Error detecting code and signal amplifiers also minimize the chance of data corruption due to electromagnetic disturbances or other noise that can alter bits of information as they travel over a communication channel.

Data communications also come with rules (protocol) that are followed by the computers of the sender and receiver. These rules ensure that the message is received and understood.

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