Which description matches a dumb terminal?

• A. A computer with CPU and memory.
• B. A handheld device with local storage.
• C. A device that senses temperature.
• D. A display monitor and keyboard, with no processing capabilities.

Answer: (D)

A dumb terminal is defined by having no processing power of its own. It is just a display monitor plus a keyboard that sends input to a separate computer and shows the output from that computer. All computing happens elsewhere, so the terminal itself has no CPU or memory to run programs.

That’s why the description of a display monitor and keyboard with no processing capabilities is the best match: it embodies the idea of a passive interface that relies on a host system for work, rather than doing any work locally. The other options describe devices with local processing or sensing capabilities, or a device that simply collects data, which is not what a dumb terminal is.
