Git is a tool that helps developers track changes in code. Unlike older systems that store only differences, Git saves snapshots of a project, making it fast and reliable.

  1. How GIt Works Internally

    Every time a commit is made, Git takes a snapshot of the project and saves it. Each snapshot has a unique ID called a hash, which keeps the history safe. Commits are linked together, forming a chain of project versions.

  2. Understanding the .git Folder

    The .git folder is hidden and created when initializing a Git repository. It stores all the information Git needs, such as files, history, and configuration. Inside, there are folders like objects and refs, and files like HEAD and config.

  3. Git Objects: Blob, Tree, Commit

    a) Blob – stores file content.

    b) Tree – stores folders and links to blobs.

    c) Commit – stores a snapshot of the project and links to a tree and parent commits.

  4. How Git Tracks Changes

    a) git add – moves changes into the staging area.

    b) git commit – saves a snapshot (commit) of the project.
