**Question:** What is the difference between RTOS and Linux? **Answer:** I explained that an RTOS (Real-Time Operating System) is designed to provide deterministic and predictable response times. It is used in systems where tasks must be executed within strict timing constraints, such as embedded controllers and real-time devices. RTOS typically has lightweight scheduling, low latency, and precise task prioritization. In contrast, Linux is a general-purpose operating system that focuses on overall system performance, multitasking, and resource management rather than strict timing guarantees. Standard Linux is not deterministic like an RTOS, although real-time patches can be applied to improve its real-time capabilities. Therefore, RTOS is commonly used for microcontrollers and time-critical embedded systems, while Linux is often used in more complex embedded platforms that require networking, file systems, and higher-level applications.
