System failure occurs when a complex system, like a computer network or transportation system, stops functioning as intended. This can happen due to various reasons, such as software bugs, hardware malfunctions, or human errors. When a system fails, it can lead to disruptions, causing inconvenience or even danger to users who rely on it. In many cases, system failures can be prevented through regular maintenance and updates. For example, keeping software up to date can fix vulnerabilities that might lead to crashes. Understanding the causes of system failure helps organizations improve their systems and ensure smoother operations in the future.
