What term refers to an unexpected problem with hardware or software?

• A. Search Engine
• B. Bug
• C. File Extension
• D. Pixel

Answer: (B)

A bug is an unexpected problem with software that causes a program to behave incorrectly, crash, or produce wrong results—and it can also arise from how software interacts with hardware. The central idea is that a bug is a flaw in the program’s code or its design that leads to undesired behavior, which engineers diagnose and fix through debugging. For example, a calculation yielding the wrong output or a feature not responding as expected are typical bug manifestations. The other terms don’t fit because a search engine is a tool for finding information, a file extension indicates a file type, and a pixel is a tiny element on a display.
