An embedded system is a specialized computer system designed to perform a specific function or a set of predefined functions within a larger mechanical or electronic system. Unlike general-purpose computers, embedded systems are developed to operate with limited resources, high reliability, and efficient performance. They are widely used in devices such as washing machines, medical equipment, automobiles, industrial control systems, smart appliances, and communication devices. An embedded system consists of both hardware and software components that work together to perform dedicated tasks. The basic components of an embedded system can be represented through the following block diagram: ``` Input Devices | | V +--------------------+ | Microcontroller | | / _______ _________ ______ _____ _________ _______ ____ ______.
