Embedded systems are the hidden heroes of our modern world, silently powering everything from smartphones and thermostats to self-driving cars and industrial robots. But understanding how these tiny computers function requires a grasp of some key terms. Let's delve into the essential embedded systems vocabulary: Microcontroller (MCU): The heart of most embedded systems, an MCU is a self-contained chip integrating a processor, memory, and input/output (I/O) capabilities. Think of it as a tiny computer designed for a specific task. Microprocessor (MPU): Similar to an MCU, an MPU is a central processing unit, but it typically lacks built-in memory and I/O functionalities. MPUs are often found in more complex embedded systems requiring higher processing power. Real-Time Operating System (RTOS): Unlike...
