What is a version control system?

Version Control System

Version control system (Vcs) is a tool or software that helps to manage different versions of source code.
Source control is another name for version control systems.

In other words, version control is a system that carries records of all file changes or file sets with respect to time so that we can easily switch to previous versions in the future.

What is Git

Git is a version control system (VCS) that helps track file changes in a simple way. Git is a free and open source distributed version control system with a simple UI design that everyone can easily understand. With the help of Git, we can track small to large projects quickly and efficiently.

• Repository: A collection of source codes or files for project work. The repository can exist in the local environment or in the form of a remote copy on another computer. The repository consists of commits.
  Working Directory: is the source code or file you see in the computer file system. When you open the project file on the code editor, you are using the file in the working directory.
• Staging Area: Staging all the changes in the current directory, used to store information about the changes you submitted. You can think of the staging area as a preparation table where Git will make the next commit.
• Branch: It is a new development line created, which is different from the main line of development. This alternative development route can be continued without changing the main line.
