Git is a distributed version control system that allows developers to track changes to their code and collaborate with others on software development projects. With Git, developers can create a copy of their code repository (a "repo") on their local machine, make changes, and then push those changes back up to a shared repository. This process makes it easy for multiple developers to work on the same codebase simultaneously without causing conflicts or losing work. GitHub is a web-based platform that provides hosting for Git repositories. It is a popular platform for open source software development, but it is also used by companies and individuals for private projects. GitHub offers a range of collaboration features, including code review tools, issue tracking, and wikis. Developers can use GitHub to share their code with others, contribute to existing projects, and discover new projects to work on. GitHub has become an integral part of the software development workflow for many developers, providing a centralized location for code storage and collaboration. It has also become a hub for the development community, with many developers using GitHub to showcase their skills and build their portfolios.
