Git is an open-source distributed version control system to track the history of different versions of the same project. It is important to keep track of the progress of the project at each step and to be able to retrieve the previous version in case of any misconduct happened in the source code by mistake.
- It is open-source software, i.e., it is licensed for collaboration and sharing because they permit other developers to make modification to the source code.
- It is a distributed version control system.
- Git is a tool, not a programming language.
- Linus Torvalds is the founder of Git and GitHub.
- Linus Torvalds is also the creator of the Linux Kernel. Linux Kernel is utilized by Linux OS (Ubuntu / Mac-OS) and Android.
- It is downloaded to your local machine.
- It is a general tool, which means, it is not dependent on any specific programming language.
- And the best part is, it is a free tool!
Need of Git
Git is a distributed version control system that saves a copy of each version, i.e., it stores a history of a project in the form of branches (the master branch is by default branch).
It empowers the developer to test and try new features without dreading the loss of the whole project. It gives the freedom to isolate testing of a code through branches. You can jump back to any of the older versions of your project. Thus, providing a safe working environment for any developer.
It is easy to share git repositories with your team member or to upload on GitHub. GitHub opens up your source code, on an online platform, for collaboration. And it maintains a nice portfolio of your work for future references.
Distributed Version Control System
Git is a Distributed Version Control System. But what does it mean?
Let’s break down the term into smaller chunks.
Git is a distributed software it means, it not only stores the files in a local system but also maintains a central repository that can easily be shared and collaborated with anyone that is also for free!
When we add new features to our project, it is very cumbersome to maintain the history of that project. But if the newly added version is creating an issue it can ruin the whole project if we do not have the previous code (the code when that feature was not added).
For example, In app-store or play-store, say, WhatsApp has released a brand new feature, then we have to download the latest version from the app-store/play-store.
In this case, if they do not maintain a version control system any corruption or failure in the feature can just smash down the whole Whatsapp. But that never really happens. Thanks to the version control system that maintains the older versions and the developer can jump back to any of the previous versions without any difficulty.
Control System :
It is a version control system because it allows the user to directly control the storage of version history, i.e, It stores a version only on user command.
Note: Saving version, merging branches is quite easy as compared to manually saving different files for different versions and manually merging them.
Benefits of Git branches
Some of the major benefits of the branch feature of Git is listed below:
- The branching feature provides an isolated environment to any changes to the source code, like adding a new feature.
- Git branches can be merged very easily to the main program.
- Git creates separate modules to work in every new branch. One module does not affect the values of another module until they are merged together.
Difference between Git and GitHub
Git and GitHub, are two different platforms, and beginners often confuse and consider them to be the same.
