What is the process of identifying errors or bugs in hardware or software called?

The process of identifying errors or bugs in hardware or software is called debugging. This involves systematically locating and correcting issues in code or hardware designs to ensure that the system behaves as expected. Effective debugging can require knowledge of the design and implementation of the software or hardware, as well as tools and methods for diagnosing problems.

Iteration refers to the process of repeating a set of steps in a design or programming process, often for refining or improving a project, rather than specifically identifying errors. Compilation is the process of converting source code written in a programming language into executable code, which is more about transforming the code than identifying bugs. Execution is the running of a program or code on a computer, which comes after the debugging stage, making sure the program works as intended during this phase is crucial.
