Data transmission, digital transmission or digital communications is the transfer of data over a point-to-point or point-to-multipoint communication channel. Examples of such channels include copper wires, optical fibers, wireless communication channels, storage media and computer buses.
Digital is defined as any data represented by a series of digits, and media refers to methods of broadcasting or communicating this information. Together, digital media refers to mediums of digitized information broadcast through a screen and/or a speaker. [1]
Aspects of digitality include nearly continuous contact with other people through cell phones, [1] near instantaneous access to information through the World Wide Web, third wave information storage (where any fragment in a text can be searched and used for categorization, such as through search engine Google), and communicating through weblogs and email.
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 ...
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]
Communication is commonly defined as the transmission of information.Its precise definition is disputed and there are disagreements about whether unintentional or failed transmissions are included and whether communication not only transmits meaning but also creates it.
Digital media, media stored as digital data Digital radio, which uses digital technology to transmit or receive; Digital television, television systems which broadcast using digital signals; Digital signal (electronics), signals formed from a discrete set of waveforms, rather than continuous ranges
A digital environment is an integrated communications environment where digital devices communicate and manage the content and activities within it. The concept is based on digital electronics systems which are integrated and implemented for a global community. [ 1 ]
