Microsoft GH-900 - GitHub Foundations

In a Git repository, a file can be in one of the following three valid states:

Committed : The file is saved in the local repository. It is part of the permanent history of the project.

Modified : The file has been changed but not yet staged or committed. It is in the working directory.

Staged : The file has been marked to be included in the next commit. It is in the staging area, ready to be committed.

These states represent the typical lifecycle of a file as it moves through the process of being edited, reviewed, and saved in Git.

GitHub Copilot is described as an AI pair programmer that offers autocomplete-style suggestions. It is a tool integrated into development environments like Visual Studio Code that helps developers by providing code suggestions as they type. Copilot can suggest entire lines or blocks of code based on the context of what you’re writing, making it a valuable assistant in coding, but not a replacement for developers.
