What Are Embedded Systems and How Do They Work?

TL;DR

Embedded systems are microprocessor-based computer systems designed to perform specific tasks, integrating both hardware and software. They are characterized by their single-function capabilities, strict constraints on size, cost, and performance, as well as real-time responsiveness. Examples include devices like fire alarms and digital watches.
