What is the difference between using Git and working with GitHub, and what are their main functional differences?

Git is a distributed version control system that works locally on your computer. It allows tracking changes in code, creating branches, merging them, and managing the project history.

GitHub is an online service (hosting) for Git repositories. It provides a web interface for storing repositories, collaborative work, task management, code review, CI/CD, and other features.

Main differences:

• Git is a tool for managing code versions locally and in remote repositories.
• GitHub is a platform for hosting Git repositories and organizing team work.

Example: you use Git to record changes and work with branches, and GitHub to push your code to a remote repository, share it with colleagues, and conduct collaborative development.
