Explanation

When a human makes a mistake writing code, it's called an ERROR. This error can introduce a FAULT (defect) in the code. When the faulty code executes, it may produce a BUG (unexpected behavior), and if this bug causes the system to deviate from specified requirements, it's a FAILURE. Defect is often used synonymously with fault or bug. So the chain is: human mistake → error → fault/defect in code → bug → failure.
