Microprocessor vs Microcontroller : Key differences

The Microprocessor (MPU) The "Brain: It is only a Central Processing Unit (CPU). External Support: It requires external RAM, ROM, and I/O ports to function. Example: Intel Core i7, AMD Ryzen (used in PCs and Laptops). Applications: General purpose (Computers, Servers). The Microcontroller (MCU) The "Whole Body": It contains the CPU, RAM, ROM, and I/O ports all on a single chip. Self-Contained: It is designed to perform specific tasks without extra components. Example: Arduino (ATMega), 8051, PIC (used in washing machines, microwaves). Applications: Task-specific (Embedded Systems)
