Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication using radio spectrum, storage media and computer buses.
Computer-mediated communication (CMC) is defined as any human communication that occurs through the use of two or more electronic devices. [1] While the term has traditionally referred to those communications that occur via computer-mediated formats (e.g., instant messaging, email, chat rooms, online forums, social network services), it has also been applied to other forms of text-based ...
In mass communication, digital media is any communication media that operates in conjunction with various encoded machine-readable data formats. Digital content can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media ...
Communications can be encoded as analogue or digital signals, which may in turn be carried by analogue or digital communication systems. Analogue signals vary continuously with respect to the information, while digital signals encode information as a set of discrete values (e.g., a set of ones and zeroes). [42]
In digital communications, a digital signal is a continuous-time physical signal, alternating between a discrete number of waveforms, [3] representing a bitstream. The shape of the waveform depends the transmission scheme, which may be either a line coding scheme allowing baseband transmission; or a digital modulation scheme, allowing passband ...

In digital communications, for example, repeating hardware was able to amplify the digital signal and pass it on with no loss of information in the signal. Of equal importance to the revolution was the ability to easily move the digital information between media, and to access or distribute it remotely.
Digital Communication Network, founded in 2016 after the same name program by the US Department of State, [2] is a 6.000 member strong collaborative network that connects professionals of the digital age from a variety of backgrounds, in order to generate ideas, tools, and products for media outlets, civil society organizations, businesses and public authorities.
