10. Operating System Types for Real-Time and Embedded Applications
Real-time and embedded systems rely on specialized operating systems that cater to their unique timing and resource requirements. Key types include Real-Time Operating Systems (RTOS), which provide deterministic performance, Batch OS designed for sequential job processing, Time-Sharing OS for multitasking, and Distributed OS for coordinated operations. Selecting the appropriate OS involves considering factors such as performance needs, memory limitations, and functionality.

What we have learnt
- Real-time and embedded systems benefit from specialized OS types optimized for performance, timing, and resource use.
- RTOS is preferred for deterministic applications; time-sharing OS fits soft real-time needs; distributed OS powers networked embedded devices.
- Proper OS selection balances latency, footprint, modularity, and hardware compatibility to meet system requirements.
Key Concepts
- -- RealTime Operating Systems (RTOS)
- Operating systems that provide deterministic performance with low latency, suitable for critical tasks.
- -- Batch Operating Systems
- Systems designed for executing a batch of jobs sequentially without real-time constraints.
- -- TimeSharing Operating Systems
- Operating systems that allow multiple users or tasks to share system resources through time-slicing.
- -- Distributed Operating Systems
- Systems that manage a group of distinct computers and make them appear as a single coherent system.
- -- Embedded Operating Systems
- Lightweight operating systems designed to operate on embedded devices with specific functionality.
