What do we call issues with systems that were not caused by an external source?

The term "bugs" is widely used in software development and IT to refer to flaws or errors in a program or system that arise internally, rather than from an external source. Bugs can manifest as unexpected behavior, incorrect results, or a failure to perform intended functions. They are typically introduced during the development process, such as through coding errors, logic mistakes, or improper handling of input data.

This term is significant in the context of software testing and debugging, where identifying and resolving bugs is essential to ensure system reliability and performance. Understanding bugs is crucial for IT support professionals, as they often need to diagnose and correct software issues to maintain optimal system operation and user satisfaction.

While other terms, such as errors or glitches, can sometimes overlap with the concept of bugs, they may not specifically imply internal faults within the code itself and can include external factors. Faults generally refer to broader categories of issues within a system, which may encompass both internal and external influences. Therefore, the most precise term for issues not caused by an external source is "bugs."
