Complete Git Guide: Understand and Master Git and GitHub - What is Commit?

The video tutorial explains the concept of Git commits, detailing their structure, purpose, and functionality. Commits are described as Git objects that store different versions of a project, allowing users to easily switch between snapshots. The relationship between commits and tree objects is highlighted, with commits acting as wrappers around tree objects in the Git database. The tutorial also covers managing multiple commits and trees, and the process of checking out files. Finally, it discusses the fields within a commit, such as author name and email, and how to configure these settings globally in Git.
