What term describes a device that contains both the needed hardware and software to perform a dedicated function?

• A. ECC
• B. Web Service
• C. Compliance
• D. Embedded System

Answer: (D)

A device that contains both the needed hardware and software to perform a dedicated function is an embedded system. These systems are built to carry out a specific task, often with real-time requirements, by tightly integrating specialized hardware with tightly coupled software. This makes them efficient and predictable for their intended job, as seen in examples like a thermostat, a microwave controller, or a car’s engine control unit. Terms like ECC (often about data integrity), Web Service (software over a network), and Compliance (adherence to standards) don’t describe a single function-specific device, so they don’t fit the description. Embedded system is the right concept because it captures the idea of a device designed to perform one dedicated function through hardware and software working together.
