Version control systems track file changes over time, enabling seamless collaboration without overwriting work. Git is the foundational tool for recording every modification, while GitHub provides an online platform to manage and share code repositories. These tools are essential for teams to work concurrently on projects, maintaining a clear history of development.

Developers use Git Bash on Windows to execute commands for initializing projects, adding files, and committing changes. Key steps include configuring user details, creating a folder, and using commands like `git init` and `git add` to start tracking work. This local setup forms the basis for managing code before syncing with a remote repository.

Pushing code to GitHub involves staging changes, creating a commit with a descriptive message, and using `git push` to upload work. Conversely, `git pull` downloads the latest updates from the remote repository. This cycle ensures teams share progress, maintain backups, and avoid conflicts, making it vital for data scientists and analysts.
