<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. (1995-02-28)

Data Communication Equipment

A data circuit-terminating equipment (DCE) is a device that sits between the data terminal equipment (DTE) and a data transmission circuit. It is also called data communication(s) equipment and data carrier equipment.

<communications, hardware> (DTE) A device which acts as the source and/or destination of data and which controls the communication channel. DTE includes terminals, computers, protocol converters, and multiplexors. DTE is usually connected via an EIA-232 serial line to Data Communication Equipment (DCE), typically a modem. 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. DTE should have a male connector and should transmit on pin three and receive on pin two. It is a curious fact that many modems are actually "DTE" according to the original standard. (1995-02-28)

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.

Telecommunications equipment (also telecoms equipment or communications equipment) are hardware which are used for the purposes of telecommunications. Since the 1990s the boundary between telecoms equipment and IT hardware has become blurred as a result of the growth of the internet and its increasing role in the transfer of telecoms data.

In computing, data (treated as singular, plural, or as a mass noun) is any sequence of one or more symbols. Datum is a single symbol of data.

Nonviolent Communication (NVC) is an approach to communication based on principles of nonviolence. It is not a technique to end disagreements, but rather a method designed to increase empathy and improve the quality of life of those who utilize the method and the people around them.

In computer science, data (treated as singular, plural, or as a mass noun) is any sequence of one or more symbols; datum is a single symbol of data. Data requires interpretation to become information.
