What is Real-Time Programming?
Real-time programming involves developing software systems that can guarantee immediate response times and strict adherence to performance constraints within a predetermined time frame. This type of programming is crucial for applications where delays can lead to significant failures or where operations must be synchronized with specific timing requirements. Real-time programmers must consider factors such as task prioritization, concurrency management, and system resource allocation to ensure the software meets its real-time criteria. The work often involves writing highly optimized and efficient code that can run on embedded systems or dedicated hardware. Real-time programming is used extensively in fields such as aerospace for flight control systems, automotive for vehicle safety systems, and multimedia for audio and video streaming.
