What are three routine faults that occur in operating systems and software applications?

Three routine faults in operating systems and software applications include memory leaks, where programs fail to release unused memory, leading to decreased performance over time; race conditions, which occur when multiple processes access shared resources simultaneously, causing unpredictable outcomes; and deadlocks, where two or more processes are unable to proceed because each is waiting for the other to release resources. These faults can significantly impact system stability and user experience.
