Advantages and Disadvantages
Advantages of Embedded Systems:
- Small size: Can fit into tiny spaces (e.g., inside a watch)
- Low cost: Much cheaper than a full computer
- Low power consumption: Battery can last months or years
- High reliability: Designed to work continuously without failure
- Real-time performance: Guaranteed instant response to inputs
- Optimized: Hardware and software designed for one specific task = maximum efficiency
Disadvantages of Embedded Systems:
- Not upgradeable: Can't add new features or change function
- Limited flexibility: Does one job only, can't be repurposed
- Difficult to update: Software fixes require hardware replacement or complex reprogramming
- Hard to troubleshoot: Limited interface makes diagnosing problems difficult
