What is Git?

A distributed version control system that tracks changes in source code during software development.

Git allows multiple developers to work on the same codebase simultaneously. Each developer has a complete copy of the repository. Key operations include commit (save changes), branch (parallel development), merge (combine branches), and push/pull (sync with remote).

Popular hosting platforms include GitHub, GitLab, and Bitbucket. Git enables code review through pull/merge requests and maintains a complete history of all changes.
