Git

Git is a distributed version control system used to track changes in code, collaborate with teams and manage project history. It allows developers to work independently on branches, merge updates and revert to previous versions when needed. Git ensures code integrity, supports parallel development, and is widely used in software engineering for efficient source code management and collaboration.
