What are the advantages and disadvantages of real time systems?

Real-time systems offer the advantage of immediate processing and response, making them essential for applications like air traffic control and medical devices where timely actions are critical. They ensure predictability and reliability, which is crucial for safety. However, disadvantages include the complexity of design and implementation, as well as the high costs associated with maintaining strict timing constraints. Additionally, real-time systems can be less flexible, making adaptation to new requirements more challenging.
