What is Git?
Git is a distributed version control system designed to track changes in source code during software development. It allows multiple developers to work on a project simultaneously, managing code versions, collaboration, and backup. Git is essential for managing different versions of projects, making it easy to revert back to previous versions or create branches to develop new features without affecting the main codebase.
