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.
The goal of keying is to transmit a digital signal over an analog channel. The name derives from the Morse code key used for telegraph signaling. Modulation is the general technique of shaping a signal to convey information. When a digital message has to be represented as an analog waveform, the technique and term keying (or digital modulation ...
Transmission of a digital message, or of a digitized analog signal, is known as data transmission. Examples of transmission are the sending of signals with limited duration, for example, a block or packet of data, a phone call, or an email.
A specific radio frequency, pair or band of frequencies, usually named with a letter, number, or codeword, and often allocated by international agreement, for example: Marine VHF radio uses some 88 channels in the VHF band for two-way FM voice communication. Channel 16, for example, is 156.800 MHz. In the US, seven additional channels, WX1 ...
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 ...
Mediated communication also includes telecommunications, radio, film, television and digital technologies. Email. Electronic mail is digital mechanism for exchanging messages through internet or intranet communication platforms. [19] The first message that was sent through a computer was on October 29, 1969, by Raymond Tomlinson. [20] Text message
Multiple low data rate signals are multiplexed over a single high-data-rate link, then demultiplexed at the other end.. In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
Digital rhetoric is an extension of human communication—taking place in a digital sphere. [1]Digital rhetoric is communication that exists in the digital sphere. It can be expressed in many different forms, including text, images, videos, and software. [2]
