What (who) is data communication - definition
Data communication
PHYSICAL TRANSFER OF DATA; TRANSFER OF DATA (A DIGITAL BIT STREAM OR A DIGITIZED ANALOG SIGNAL) OVER A POINT-TO-POINT OR POINT-TO-MULTIPOINT COMMUNICATION CHANNEL

Data transmission and data reception or, more broadly, data communication or digital communications is the transfer and reception of data in the form of a digital bitstream or a digitized analog signal 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.

<communications, hardware> (DCE) The devices and connections
of a communications network that connect the communication
circuit between the data source and destination (the {Data
Terminal Equipment} or DTE). A modem is the most common
kind of DCE.
Before data can be transmited over a modem, the DTR (Data
Terminal Ready) signal must be active. DTR tells the DCE that
the DTE is ready to transmit and receive data.
DCE and DTE are usually connected by an EIA-232 {serial
line}. It is necessary to distinguish these two types of
device because their connectors must be wired differently if a
"straight-through" cable (pin 1 to pin 1, pin 2 to pin 2 etc.)
is to be used. DCE should have a female connector and should
transmit on pin two and receive on pin three. It is a curious
fact that many modems are "DTE" according to the original
standard.
