An embedded system refers to a dedicated computer designed to perform a specific function within a larger system, often as part of a hardware device. Unlike general-purpose computers, embedded systems are typically optimized for tasks such as control, monitoring, or automation. They integrate both software and hardware components, and their functionalities are often constrained by limited resources and real-time performance requirements. These systems are found in various applications, including appliances, automobiles, and medical devices, where they enhance functionality and efficiency.
