Embedded systems are often categorized based on their performance requirements and functional complexity:

An embedded system typically consists of a microcomputer (microcontroller or microprocessor) interfaced with sensors to collect data and actuators to perform physical actions. Unlike general-purpose computers, these systems are application-specific and often subject to strict performance, power, and real-time constraints. Classification of Systems

: Connected to a network (LAN or WAN) to share data (e.g., IoT devices).
