A microprocessor is the central processing unit of a computer system on a single integrated circuit. Microcontrollers integrate CPU, memory, and peripherals on one chip and are widely used in embedded systems, IoT devices, robotics, and automation.
Microprocessors and microcontrollers form the foundation of modern computing and embedded systems. They are used in smartphones, automobiles, medical equipment, industrial automation, and consumer electronics. Understanding processor architecture, instruction sets, and hardware interfacing is essential for computer engineering students and embedded system developers.
