computer bug
A software bug is an error, flaw or fault in computer software that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of finding and correcting bugs is termed “debugging” and often uses formal techniques or tools to pinpoint bugs.

She was also a United States Navy rear admiral, helped develop COBOL — one of the first high-level programming languages — and invented the first compiler, a program that translates programming code to machine language.
Are there bugs in peanut butter?

A bug is a general term used to describe any unexpected problem with hardware or software. For example, Grace Hopper logged and taped a moth bug in a log book that caused issues with the Mark II.
What is bug defect error?
Testing is the process of identifying defects, where a defect is any variance between actual and expected results. “A mistake in coding is called Error, error found by tester is called Defect, defect accepted by development team then it is called Bug, build does not meet the requirements then it Is Failure.”
What is database bug?
A bug indicates a fault, error or failure in the software/system being built that produces unexpected results. A bug identified needs to be tracked and fixed to ensure optimum quality in the software/system being developed.
Why are errors called bugs?
Operators traced an error in the Mark II to a moth trapped in a relay, coining the term bug. This bug was carefully removed and taped to the log book. Stemming from the first bug, today we call errors or glitches in a program a bug. Hopper did not find the bug, as she readily acknowledged.
