What are the basic components of an embedded system? Explain the classification of embedded systems.

Basic Components of an Embedded System:

1. Microcontroller/Microprocessor: Acts as the brain of the system, executing instructions and controlling hardware components.
2. Memory: Stores program instructions, data, and configurations.
3. Input Devices: Collects input from sensors, switches, or other devices.
4. Output Devices: Displays information or controls external systems through actuators.
5. Communication Interfaces: Facilitates communication with external devices or networks.

Classification of Embedded Systems:

1. Based on Performance and Complexity:

   • Small-scale Embedded Systems: Simple systems with limited resources, often single-function devices like a thermostat.
   • Medium-scale Embedded Systems: More complex systems with moderate resources, such as consumer electronics like digital cameras.
   • Large-scale Embedded Systems: Sophisticated systems with abundant resources, like automotive control systems or industrial automation.

2. Based on Functionality:

   • Real-time Embedded Systems: Responds to inputs and produces outputs within a specified time frame, critical for applications like automotive safety systems.
   • Networked Embedded Systems: Interconnected systems that communicate with each other or external networks, like smart home automation systems.
