What term describes a display monitor that has no processing capabilities?

The term that describes a display monitor with no processing capabilities is a dumb terminal. A dumb terminal is essentially a simple output device that allows users to interact with a mainframe or server. It does not have its own processing power or more complex functionalities; instead, it relies entirely on the server for processing data. This is crucial in environments where centralized computing is utilized, as the terminal itself does not manage applications or data, making it a straightforward device focused solely on displaying information received from the main system.

The other terms do not accurately capture the definition of a dumb terminal. A thin client, while also reliant on a server, typically has some processing power for lighter tasks and can often run basic applications locally. A smart display implies advanced features and capabilities, such as built-in processing power or connectivity options, that far exceed those of a dumb terminal. A workstation is a fully equipped computer designed for complex tasks, capable of processing its own applications and data, which contrasts sharply with the function of a dumb terminal.
