GIT is a distributed version-control system for tracking changes in source code during software development. It is designed for coordinating work among programmers, but it can be used to track changes in any set of files. Its goals include speed, data integrity, and support for distributed, non-linear workflows.
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
By far, the most widely used modern version control system in the world today is Git. Git is a mature, actively maintained open source project originally developed in 2005 by Linus Torvalds, the famous creator of the Linux operating system kernel. A staggering number of software projects rely on Git for version control, including commercial projects as well as open source. Developers who have worked with Git are well represented in the pool of available software development talent and it works well on a wide range of operating systems and IDEs (Integrated Development Environments).
If you are a graphic or web designer and want to keep every version of an image or layout (which you would most certainly want to), a Version Control System (VCS) is a very wise thing to use. It allows you to revert selected files back to a previous state, revert the entire project back to a previous state, compare changes over time, see who last modified something that might be causing a problem, who introduced an issue and when, and more. Using a VCS also generally means that if you screw things up or lose files, you can easily recover. In addition, you get all this for very little overhead.
You can think of a version control system (short: “VCS”) as a kind of “database”. It lets you save a snapshot of your complete project at any time you want. When you later take a look at an older snapshot (let’s start calling it “version”), your VCS shows you exactly how it differed from the previous one.
A version control software saves all the changes in a repository. Hence, if the developers make a mistake, they can undo it. At the same time, they can compare the new code with a previous version(s) to resolve their grievance. This can reduce human errors and unintended consequences to a great extent. A great fit for any web development company around the globe.
