What is Git?

Distributed Version Control

Git is a powerful distributed version control system created by Linus Torvalds in 2005. It allows developers to track changes, collaborate efficiently, and manage code history with complete confidence.


Every developer has a full copy of the project history, enabling fast branching, merging, and offline work. Git powers modern software development and is the backbone of platforms like GitHub, GitLab, and Bitbucket.

  • Repositories (Repo): A folder containing all project files and complete history.
  • Commits: Snapshots of your code at specific points in time with unique IDs.
  • Branches: Parallel versions of your code for features or experiments.
  • Merge: Combining changes from different branches.
  • Pull Requests: Propose and review changes before merging into main.
  • Clone: Create a local copy of a remote repository.
  • Push & Pull: Share your changes (push) and get latest updates (pull).
