tiedonsiirtopäätelaite

Tiedonsiirtopäätelaite, often translated as data terminal equipment (DTE), refers to a device that serves as a user interface or endpoint for communication networks. It is the part of a communication system that initiates, processes, or receives data. Examples of tiedonsiirtopäätelaite include computers, smartphones, printers, and modems when they are connected to a network.

The primary function of a tiedonsiirtopäätelaite is to convert data into a format suitable for transmission over a network and to convert received data back into a usable format for the end-user or application. This often involves a combination of hardware and software components. For instance, a computer acts as a DTE by running applications that generate data, and its network interface card (NIC) handles the physical transmission and reception of signals.

In the context of telecommunications, the term DTE is often contrasted with Data Circuit-Terminating Equipment (DCE), which provides the connection to the network. In a typical point-to-point connection, the DTE is connected to the DCE, which then handles the communication over the network infrastructure. This separation of roles helps in standardizing network interfaces and protocols. The evolution of networking has seen the lines between DTE and DCE blur with the integration of functionality into single devices, but the conceptual distinction remains important for understanding network architecture.
