Which process involves correcting errors that occur in a computer program?

The process that involves correcting errors in a computer program is known as debugging. Debugging is a systematic method used by developers to identify, isolate, and fix issues or bugs within the code. This process typically begins after testing has revealed that problems exist, but it can also occur during the development phase as the programmer writes code.

Debugging encompasses a variety of techniques, including reviewing code, using debugging tools to trace program execution, and logging errors to pinpoint where issues arise. This is crucial because while testing can show that bugs are present, debugging is the essential next step to actually resolve those issues, allowing the program to run smoothly and as intended.

Other options may relate to aspects of handling errors or validating functionality, but they do not specifically focus on the correction phase itself, which is the defining characteristic of debugging.
