The process of finding, analyzing, and fixing errors or 'bugs' in computer programs. It involves identifying what's causing unexpected behavior and correcting the code to make it work as intended.
The term 'bug' for a computer error was popularized by Admiral Grace Hopper in 1947 when she found an actual moth trapped in a computer relay. 'Debugging' naturally followed as the process of removing these 'bugs' from programs.
Debugging is like being a detective solving a mystery - you have clues (error messages, unexpected output), you form hypotheses about what went wrong, and you test your theories until you find the culprit. Every programmer is part-time detective!
