Which component is called DTE in networking?

In networking, the term DTE stands for Data Terminal Equipment. DTE refers to devices that serve as the endpoint for a data connection and are responsible for the initiation, termination, or processing of information in the communication. Typically, this includes devices such as computers, printers, or any customer-end devices that send or receive data over a network.

The DTE connects to the Data Communication Equipment (DCE), which is often the network equipment managed by a service provider, such as routers or switches. The correct association with DTE helps in understanding network layouts and configurations, particularly in scenarios involving serial connections or point-to-point links.

In contrast, service provider routers, switching hubs, and cloud gateways are considered DCE as they facilitate the transmission of data rather than being the final endpoint or terminal for the data. Therefore, identifying the customer end device as DTE aligns with the definitions and function of the terms in networking.
