Which term is an electronic device that receives data, processes data, stores data, and produces a result?

• A. Cloud
• B. Computer
• C. Hardware
• D. Router

Answer: (B)

The fundamental idea is that a computer is an electronic device that handles input, processes instructions, stores data, and produces output. This combination of four basic functions—receiving data (input), performing operations (processing), keeping data (storage), and showing results (output)—is what defines a computer as a complete computing system.

Why this fits best: A computer is designed to take in information from keyboards, mice, or sensors, run programs that transform that information, save data to memory or storage for later use, and display or transmit the results. It’s the whole package that makes it possible to perform a wide range of tasks from simple calculations to running complex software.

Why the other terms don’t fit as the single device described: The cloud isn’t one physical device; it’s a networked set of services and data centers accessed over the internet, not a standalone gadget that you can point to as the device performing all four functions for a user. Hardware refers to the physical components, which enable processing and storage but don’t by themselves define the complete data cycle or produce outputs unless arranged as a system with software. A router is a specialized network device that directs data traffic between networks and doesn’t perform general-purpose data processing or long-term storage to produce user-facing results.
