26. What is a patch?

A patch is a file that consists of a list of differences between one set of files and another. All code changes, additions, or deletions to Drupal core and contributed modules/themes between developers are done through patches.
The differences are presented in a structured, standard way, which means that a program (also named patch) can be used to apply the changes to another copy of the original file.
