Data communication is the transfer of data between devices using the medium of transmission. It could be via wired media, like coaxial or twisted pair wire cable, or wireless media such as optical fibers or radio waves. The data has to be encoded, encapsulated, and transmitted by the sending device then decoded and decapsulated at the receiving device. This is similar to the transmission of analog signals however, it is more complicated and focuses on the exchange of binary data (1s and 0s).

To increase efficiency within an organization, companies are using data communication to share information more efficiently with dispersed users. For instance, a car manufacturer needed to share information to 6’000 non-trained and dispersed spare parts dealers in order to ensure that their inventory was in line with demand and reduce the amount of waste. This required communication over a network that was not designed for data communications and an app for mobile that was difficult to navigate for new users.

Effective data communication begins with understanding your audience and how they perceive the data. It involves creating visuals that aid in telling the story, giving contextual information, and articulating the data’s insights using a clear narrative. It also involves tailoring content to the specific audience based upon their hierarchy, technical knowledge and level of interest. In addition, it requires breaking the boundaries of creativity to make data-driven communications more impactful and memorable.
