Data Communication – The Lifeblood of Digital Networks

08 Avr Data Communication – The Lifeblood of Digital Networks

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

Hardware in a data communications circuit will use different techniques to send data effectively. This includes multiplexing and desmultiplexing. These are processes that combine or separate signals and transmit them as one composite signal. This maximizes the utilization of bandwidth and reduces costs. Error detecting code and signal amplifiers can also limit the chance of data corruption due to electric disturbances, or even momentary electrical noises that can alter bits of data when they travel through the channel of communication.

Data communications also contain an array (protocol) of rules that are adhered to by both the sender’s and receiver’s computers. These rules ensure that the message is understood and accepted without error.

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