Which of the following is typically considered a back-end device?

A server is typically considered a back-end device because it plays a crucial role in managing, processing, and storing data that can be accessed by front-end devices like desktops, tablets, and smartphones. Servers handle the behind-the-scenes functions essential for supporting applications, databases, and services that users interact with on their front-end devices.

In contrast, front-end devices, such as desktops, tablets, and smartphones, serve as the user interface for accessing the server's resources. They are designed for user interaction and display information processed by the server. Thus, while they are essential for the overall system, they do not perform the same back-end functions as a server. Understanding the distinction between back-end and front-end devices is critical for recognizing how data flow and processing occur in information systems.
