Comment (computing)
In computing, a comment is information in a file that is generally ignored but may be helpful to human users of the file. The structure, scope and processing applied to this information depends on the syntax and conventions used to describe the information contained in the file.
A common occurrence are the comments that appear in the source code of a program. In this case the syntax of the programming language specifies the form that comments can take. Such comments could be said to be computer programming comments.
Another common usage are the comments that appear in an initialization or configuration file.
Word processors often support an option that enables writers of documents to effectively write notes to themselves about the material they are writing. These notes are not visible to a reader of the document unless explicitly asked for.
