What is the primary function of DTE in a network?

The primary function of Data Terminal Equipment (DTE) in a network is to serve as an endpoint or user device. This includes devices such as computers, terminals, or any other equipment that generates or receives data in a network communication. DTE communicates with Data Communication Equipment (DCE), which provides the necessary infrastructure to facilitate the data transmission.

DTE is responsible for converting the data into a format suitable for transmission over the network and often handles the signaling for initiating and terminating communication. It is a key component in the overall functionality of a network because it represents the user end of the communication interface. By understanding DTE's role, one can appreciate its critical function in ensuring data can be correctly inputted into the network and received by the appropriate destination.
