**What does "embedded systems" refer to in electronics?**
Embedded systems refer to specialized computing systems integrated into larger devices to perform dedicated functions. Unlike general-purpose computers, these systems are designed for specific tasks, often with real-time computing constraints. Examples include microcontrollers found in appliances, automotive systems, and medical devices. Embedded systems combine hardware and software tailored to their applications, focusing on efficiency, reliability, and low power consumption. Their significance lies in enabling smart functionality across various industries, enhancing automation, and improving performance in everyday devices.
