Git is a distributed version control system that enables developers to track changes in source code, collaborate on projects, and maintain a complete history of every modification made to a codebase. Created by Linus Torvalds in 2005, Git has become the industry standard for source code management, powering workflows at organizations of all sizes from solo developers to enterprise teams.
Unlike centralized version control systems, Git gives every developer a full copy of the project repository, including its entire history. This distributed architecture allows developers to work offline, create branches for experimental features, and merge changes back into the main codebase with minimal conflict. Key concepts in Git include commits, branches, merges, rebases, and pull requests, all of which facilitate parallel development and code review.
Git integrates seamlessly with hosting platforms like GitHub, GitLab, and Bitbucket, which add collaboration features such as issue tracking, continuous integration pipelines, and code review tools. Mastering Git is considered an essential skill for modern software developers, as it underpins nearly every professional development workflow and DevOps pipeline in use today.
