Program errors are common in computer systems and can be the cause of system crashes and malfunctions. There are several synonyms for program errors, including bugs, glitches, faults, defects, issues, and flaws. Bugs refer to errors that cause unexpected behavior in software, while glitches are sudden and temporary errors that occur in computer systems. Faults and defects are more permanent errors that affect the functionality of a program. Issues refer to problems that arise while using software or hardware. Flaws are programming errors that produce unwanted results, rendering a program dysfunctional. Regardless of the term used, program errors can be frustrating and time-consuming to identify and fix.
