Git is a distributed version control system that allows developers to work locally and share code changes with remote repositories. It uses a local working directory, staging area, and local repository that are linked to remote repositories hosted online. Developers add files to the staging area and commit changes to the local repository, then push updates to remote repositories for sharing with other collaborators, who can fetch and merge any new changes into their local repositories.
