Which device is considered Data Terminal Equipment (DTE)?

In networking terminology, Data Terminal Equipment (DTE) refers to devices that serve as the source or destination of data. These devices are often responsible for generating or consuming data directly. A computer fits this definition as it actively processes data, runs applications, and interacts with users, making it an essential part of the communication process by converting data into a format that can be transmitted over a network.

The other options, while important in networking, do not strictly fall under the DTE classification. A printer is typically viewed as a peripheral device that outputs data received from a computer, rather than directly processing it. A server functions more as a data source and can also deliver data to DTE devices, but it is often categorized differently due to its role in serving multiple clients. A router, on the other hand, is primarily a Data Communication Equipment (DCE) device, responsible for directing data packets between networks rather than generating or consuming data directly as DTE does.

Thus, within the context of this question, a computer is the most fitting example of Data Terminal Equipment due to its role in the data communication process.
