Final Answer:
A micro-controller is best described by option (C): a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.
Step-by-step explanation:
Option (C) accurately defines a micro-controller as a compact computing device housed on a single integrated circuit (IC). It typically includes a central processing unit (CPU), memory (RAM and/or ROM), and programmable input/output peripherals. Micro-controllers are commonly used in various applications, such as embedded systems, automation, and IoT devices, where a compact and efficient computing solution is required.
Options (A), (B), and (D) do not precisely capture the essence of a micro-controller. Option (A) describes a small CPU made of transistors and conductors of heat and sound sensors, which is not an accurate representation of a micro-controller's comprehensive functionality. Option (B) suggests portable circuits capable of making other circuits, which is a more generic description and doesn't specifically convey the integrated nature of a micro-controller. Option (D) mentions a small chip made of silver, which does not provide a comprehensive and accurate definition of a micro-controller.
Understanding the nature and functionality of a micro-controller is essential in the field of electronics and embedded systems. It serves as the brain of many devices, providing the necessary computational capabilities to perform specific tasks efficiently and with minimal hardware complexity.
