Data Communication – The Lifeblood of Digital Networks

In our increasingly connected digital world data communication is the vital ingredient that connects us. Understanding how different types of data transmission work is crucial to constructing reliable and efficient networks. Different methods determine the method by which data is transmitted.

To transfer data efficiently the hardware of a data communication circuit employs a variety of techniques such as multiplexing and demultiplexing, which are processes that combine and separate signals into single composite ones for transmission, and then back into the individual components. This increases bandwidth and reduces costs. Error detecting codes and signal amplifiers also minimize data corruption from noise or momentary electrical disturbances that could alter bits of data while they travel along the communication channel.

Data communications also have rules (protocol) that are followed by both the computer systems that transmit and receive data. These rules help bigdataroom.net ensure that the message is understood and accepted without error.

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