Explain the components of an embedded system. Also list the basic characteristics of embedded systems. Explain the characteristics of an embedded operating system.

Components of an embedded system include:

1. Processor (CPU): Executes instructions and processes data.
2. Memory: Stores program instructions and data temporarily (RAM) and permanently (ROM/Flash).
3. Input/Output Interfaces: Connects the embedded system to external devices such as sensors, actuators, and displays.
4. Software: Includes the embedded application software and possibly an operating system.
5. Power Supply: Provides electrical power to the system.

Basic characteristics of embedded systems:

1. Real-time Operation: Must respond to inputs and events within specific time constraints.
2. Low Power Consumption: Designed to operate with minimal power usage.
3. Limited Resources: Typically have limited processing power, memory, and storage.
4. Dedicated Functionality: Built to perform specific tasks or functions.
5. Cost-effective: Designed to be cost-effective for mass production.

Characteristics of an embedded operating system:

1. Real-time Capability: Provides deterministic response times for critical tasks.
2. Small Footprint: Requires minimal memory and storage resources.
3. Efficiency: Optimized for low-power and resource-constrained environments.
4. Customization: Allows customization for specific hardware configurations and application requirements.
5. Reliability: Must be highly reliable and stable for continuous operation in embedded applications.
