What generic term describes a programmable electronic device that can store, retrieve, and process data?

• A. Computer
• B. Calculator
• C. Processor
• D. Microcontroller

Answer: (A)

Storing, retrieving, and processing data with programmable instructions describes a computer. A computer combines memory to hold data and programs with a processor that fetches and executes instructions, enabling a wide range of tasks from simple calculations to complex software applications. A calculator typically focuses on arithmetic and offers limited program storage or general-purpose processing. A processor by itself is just the CPU; without memory and I/O, it can’t store data or run programs as a complete system. A microcontroller is a compact, embedded computer on a single chip designed for specific tasks, but the broad, generic term that covers all such programmable data-manipulation devices is computer. That broad applicability makes it the best fit.
