What is Git and Github

 

What is Git?

Git is a free and open-source version control system used widely by the programmers these days. Now, what is a version control? It is the management of changes to documents, computer programs, large web sites, and other collections of information. For instance, as a programmer, we keep the tract to code changes-basically, save an initial version of our code into Git. And during the update of the code, we can save it into Git again, and again and again. This process, help us to look back at all of the changes we have made over the time. Further, this process helps us to see and understand the changes when we made during the particular time, as well as to track down bugs, or go back to a previous version.
