I am a newbie to here, and I have a question about microcontroller and microprocessor to be solved.

I am not quite good at electronics, so I cannot quite understand the differences between a microcontroller and a microprocessor.

A microcontroller is a small computer on a single integrated circuit that contains a processor core, memory, and programmable input/output peripherals. A microprocessor, on the other hand, is a computer's central processing unit (CPU) on a single integrated circuit. In simple terms, a microcontroller is a self-contained system that includes a processor, memory, and input/output peripherals, whereas a microprocessor is just the processor and is used as the brain of a larger system that requires external memory and input/output devices.
