Which statement best describes dedicated devices?

• A. Devices designed to perform one specific task
• B. Computers that provide services to other computers
• C. A portable computer
• D. A device that processes data

Answer: (A)

Dedicated devices are built to perform one specific task. Because of that single purpose, their hardware and software are tailored for that job, making them efficient, reliable, and often cheaper to operate for that task than general‑purpose computers. This exact focus is what the statement describes. A portable computer, by contrast, is designed to handle many kinds of tasks. A device that processes data is a broad description that can apply to many different machines and isn’t limited to a single function. A computer that provides services to other computers refers to networks or servers, which is a different concept from being dedicated to one task.
