Vxworks provides characteristics like Deterministic,Multitasking, Fast Context Switching, Support for Preemptive Based SCHEDULING Support for Multiple Priority level,Support for Inter Task Communication, Support for Inter Task SYNCHRONIZATION, Low Interrupt LATENCY Low Memory Footprint, SCALABLE

Which makes intertask communication faster and context switching latency is REDUCED because, all tasks resides in common address space,no swaping and paging of memory is used. Vxworks can be scaled, unnecessary components can be easily excluded.memory usage will be greatly reduced because of this feature.

Vxworks is extendable, new components can be added like a task.
