⚡ RTOS (Real-Time Operating System)

🟢 Deterministic → Predictable response
🟢 Priority-based scheduling → Tasks handled on urgency
🟢 Low latency → Immediate, reliable execution
🟢 Lightweight → Uses fewer resources
🟢 Use Cases → Embedded systems, robotics, automotive
🟢 Examples → FreeRTOS, VxWorks, RTEMS

💻 GPOS (General-Purpose OS)

🔵 Non-deterministic → Best effort, not predictable
🔵 Fair scheduling → Time-sharing among tasks
🔵 Higher latency → Slower than RTOS in critical tasks
🔵 Resource heavy → Needs more CPU & memory
🔵 Use Cases → PCs, laptops, servers
🔵 Examples → Windows, Linux, macOS

📌 Quick Takeaway

• RTOS = Fast, predictable, reliable → Best for real-time embedded & mission-critical apps.
• GPOS = Flexible, user-friendly → Best for general computing & multitasking.

👉 Tip for Students:
If you want to build a career in Embedded Systems & IoT, start learning RTOS concepts (e.g., FreeRTOS) because industries demand deterministic control & multitasking.
