Git is a distributed version control system that tracks code changes and manages team collaboration. Each developer maintains a complete project copy, enabling offline work and reliable history. It's the core technology behind platforms like GitHub and GitLab.

Git Bash provides a command-line interface for Windows users, offering a Unix-like shell to run Git commands. Basic workflow starts with `git init` to create a repository, `git add` to stage changes, and `git commit` to save snapshots. Regular `git status` checks keep you informed.

Collaboration relies on remote repositories. Teams clone projects, push local commits, and pull updates. Branching isolates feature work, while pull requests facilitate code review. The standard workflow—clone, branch, commit, push, review via PR, and merge—keeps projects organized and traceable for team development.
