What is the function of a computer bug?

A computer bug refers to a flaw or unintended behavior in a software program that can cause it to produce incorrect or unexpected results or to behave in unintended ways. The primary function of identifying a computer bug is to highlight faults or errors within the program's code. When a bug is detected, it signals to developers that there is a problem that needs to be addressed, thereby improving the software's overall quality and reliability.

Understanding bugs is crucial in software development, as they can arise from various sources such as logical errors, syntax mistakes, or unexpected interactions between different parts of the program. By recognizing and fixing these bugs, developers can enhance the software's performance and usability, ensuring that it operates as intended.
