Data transmission (also data communication or digital communications) is the transfer of data (a digital bitstream or a digitized analog signal) over a point-to-point or point-to-multipoint communication channel. Data communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, and vice versa. It enables the movement of electronic or digital data between two or more nodes, regardless of geographical location, technological medium or data contents. Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a.

The messages are either represented by a sequence of pulses by means of a line code baseband transmissionor by a limited data communications of continuously varying wave forms passband transmissionusing a digital modulation method.
The passband modulation and corresponding demodulation also known data communications detection is carried out by modem equipment.
According to the most common definition of digital signal, both baseband and data communications signals representing bit-streams are considered as digital transmission, while an alternative definition only considers the baseband signal as digital, and passband transmission of digital data communications as a form of digital-to-analog conversion.
Data transmitted may be digital messages originating from a data source, for example a computer or a keyboard. It may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream for example using pulse-code modulation PCM or more advanced source coding analog-to-digital conversion and data compression schemes.
What is Data Communications (DC)? - Definition from Techopedia
This source data communications and decoding is carried out by codec equipment. Serial and parallel transmission[ data communications ] In telecommunications, serial transmission is the sequential transmission of signal elements of a group representing a character or other entity of data.
Digital serial transmissions are bits sent over a single wire, frequency or optical path sequentially.
Because it requires less signal processing and less chances for error than parallel transmission, the transfer rate of each individual path may be faster. This can be used over longer distances as a check digit or parity bit can be sent along it easily.
It enables data communications movement of electronic data communications digital data between two or more nodes, regardless of geographical location, technological medium or data contents.
