Bug

A bug is an unexpected problem with software or hardware. Typical problems are often the result of external interference with the program’s performance that was not anticipated by the developer. Minor bugs can cause small problems like frozen screens or unexplained error messages that do not significantly affect usage. Major bugs may not only affect software and hardware, but could also have unintended effects on connected devices or integrated software and may damage data files.
