What is Git? Git Tutorial Guide for Beginners

What is Git?

Git is the most popular version control system by far worldwide that helps developers to manage changes in the source code over time. It was discovered in 2005 by famous Linux creator Linus Torvalds. Git is a free open source tool based on the distributed architecture that facilitates changes and keeps the complete history of every new version initiated in the repository. Other than this, Git has been discovered with performance, security, and flexibility in mind.

What is the Benefits & Features of Git?

  • Version Control
  • Performance
  • Flexibility
  • Security

Git Performance

GIT has very interesting performance characteristics when compared to other similar tools or alternatives available in the market. The algorithms implementation is also done wisely that informs you about changes and their access patterns too. As we know that source code is modified frequently over time and Git takes care of each edited file and version metadata objects.

Take an example, where you wanted to add few features in the upcoming version of a software that was released earlier. Suppose, you have added one feature with the complete description and committed those changes.

Now you started on another featureand commits those changes too. If you will check the record then each feature will be saved in the repository as different pieces of work. This must be understood how performance characteristics are optimized and managed in Git. Let us move to the Flexibility and Security features now.

Git Flexibility

Flexibility is the major requirement and ultimate goal of any design project today. Git assures flexibility in multiple ways like non-linear workflows development, suitable for each project instead of its size, and compatible with a plenty of existing systems too.

Git Security

Keeping your source code secure is the top priority for Software organizations. Your source code is kept secured in the repository with cryptographic hash algorithms. This security technique not only takes care of your code but makes sure that History is completely traceable.

Version control with GIT

Git is the best VCS (Version Control System) available so far with endless benefits and security tactics. Here are few popular reasons why version control with Git is considered as the preferable choice when compared to other alternatives –

  • Most of the software team believes that Git is highly favorable in terms of performance, security, functionalities, and the flexibility.
  • Git is used worldwide and a large number of software developers already have the Git experience and there is no need for extensive training when people already know about it.
  • If you are a new software developer and wants to build skills especially with version control then Git is just the perfect choice.
  • Git is a reliable open source project and a number of organizations depend on the tool to maintain their product quality and the overall project costs too.

Git Criticism

One of the most popular criticisms of Git is that it can be difficult to learn. Few terminologies are so difficult that they could not be understood by the new software developers at all. For this purpose, Companies need to organize proper training sessions and make them realize the actual importance of the tool.

With this discussion, you must be sure on various concepts like version control, Git, and why it is good for the software team or organizations as well. Once you understood all these concepts deeply, this is the time to learn Git installation step by step for practical learning of the tool.
