Comments in programming serve the crucial function of providing explanatory notes for human readers. They are non-executable lines of text within the code that offer insights, context, or clarification about how a certain piece of code functions, why it was written in a particular way, or what specific sections of the code are intended to accomplish. This is particularly important in collaborative environments where multiple programmers may work on the same codebase, as it helps others to understand the intent behind complex logic or specific implementations.

By including comments, developers can make the code more maintainable and easier to read, which is important for debugging and enhancing code in the future. Clear documentation through comments can significantly reduce the time it takes for someone new to a project to grasp its structure and functionality.

In contrast, executing code, indicating errors, and speeding up execution are not roles served by comments. Comments do not influence how a program runs or its performance; rather, they are purely informational and beneficial for the human aspect of programming.
