What is Git?

Git is a type of version control system (VCS) that helps to track the file changes in an easy manner. Git is a free and open-source distributed version control system that has a simple UI design that everyone can understand easily. With the help of Git, we can track small to very large projects with speed and efficiency.

• A repository is a Collection of the Source code or files of the project work, Repositories can exist either in the local environment or in the form of a remote copy on another computer. A repository is made up of commits.
• Working Directory is the source code or files that you see in your computer's file system. When you open your project files upon a code editor, you're working with files in the Working Directory.
• Staging Area: A Stage all Changes in the Current directory that stores information about Changes that you commit. You can think of the staging area as a prep table where Git will take the next commit.
• Branch is a new line of development is created that diverges from the main line of development. This alternative line of development can continue without altering the main line.
