Use Cases and Deployment Scope
Git is a software version control system that enables distributed collaboration of engineers working all over the world. It allows for development on parallel features, acting as the source of truth for code, and also detects and helps solve conflicts that might arise from collaboration on the same files.
I'd say Git is one of those systems that are pretty much omnipresent when it comes to the Tech industry at this point. I haven't come across a simpler, better distributed version system yet.
