What does "DTE" stand for in data communication?

In data communication, "DTE" stands for Data Terminal Equipment. This term is used to refer to devices that serve as endpoints in a communication network, typically functioning as either the source or destination of data. Examples of DTE include computers, terminals, and printers, which send or receive data through a communication channel.

DTE is an important concept as it contrasts with Data Communication Equipment (DCE), which serves to connect the DTE to the transmission medium and facilitate the data transmission process. Understanding the role of DTE helps in network design and communication system configurations, as it enables technicians to determine how devices interact with each other within the network.

The other options do not accurately define the established term used in this context. Data Transfer Entity and Digital Transmission Endpoint are not recognized standard definitions in data communication. Direct Technical Exchange implies a specific mechanism or method of inter-device communication rather than a type of equipment.
