Data communication is the transfer of data between devices by using an transmission medium. It can be accomplished through wired media like twisted-pair cable, coaxial cable, or wireless media such as radio waves or optic fibers. The data needs to be encoded, encapsulated and transmitted by the device sending it followed by decoding and decapsulation at the receiver device. This procedure is similar to analog signal transmission, but it is more complex and focuses on binary data (1s & 0s).
To improve efficiency within an organization, companies are using data communication to share data more effectively with dispersed users. For instance, an automotive manufacturer needed to communicate information to 6’000 non-trained and dispersed dealers of spare parts in order to make sure that stock is in line with demand and reduce waste products. This required communication using an unoptimized network for data transfer and the use of a mobile app that was difficult for new users to navigate.
Effective data communication starts with understanding the audience’s view of the data. It involves creating visualizations to help tell the story, providing context-based information, and articulating information in a clear and concise manner. It also involves adjusting the content to the particular audience depending on their level of hierarchy, technical proficiency, and level of interest. Additionally, it is about pushing the boundaries of creativity to make data communication more impactful and memorable.
