What is Git?

Git is a distributed version control system that allows developers to track changes to their codebase, collaborate with others, and manage project versions effectively. Developed by Linus Torvalds in 2005, Git has become the de facto standard for version control in the software development industry.



What is GitHub?

GitHub is a web-based platform built on top of Git, providing additional features for collaboration, project management, and code hosting. It serves as a central hub for developers to store, share, and collaborate on Git repositories.
