What is Git and why is it used in software development?
Updated Apr 23, 2026
Short answer
Git is a distributed version control system used to track changes in code and collaborate with multiple developers.
Deep explanation
Git allows developers to track code history, revert changes, and collaborate without conflicts. It uses snapshots instead of diffs and enables branching and merging efficiently. Each developer has a full copy of the repository, making it distributed and resilient.
Real-world example
Teams working on the same project can manage code changes without overwriting each other's work.
