Broken links are links that do not lead to an existing page. They will appear red like this. There is a page to find these broken links, and they would be Special:Wantedfiles, Special:Wantedcategories, Special:Wantedpages, Special:Wantedtemplates, and Category:Pages with broken file links.

These need to be empty for maintenance purpose, which is why I tend to remove them from people's user pages, comments, etc. This is because I create redlinks myself through other maintenance tasks such as Special:Unusedimages and so on.

Hope that answers your question.
