Understanding the World of GitHub: What is it and How it Works

GitHub, a subsidiary of Microsoft, is the world’s leading software development platform, hosting over 200 million repositories by 73 million developers as of 2021. At its core, GitHub is a web-based version control and collaboration platform that empowers developers to host, review, and collaborate on code, making it easier for them to build and ship software. In this glossary page, you’ll get to know the definition of GitHub, learn how it works, understand its benefits, explore various use cases, uncover best practices, and find the most recommended books about it.

“GitHub is the largest code host in the world, with 3.4 million users. It’s a place that most developers are extremely familiar with and is a place where developers love to contribute.” – Satya Nadella, CEO of Microsoft

What is GitHub? Definition of Github

GitHub is a web-based hosting service that enables developers to store, manage, and control their code using Git, a popular distributed version control system. It offers a platform where users can collaborate on code projects, contribute to open-source software, and track changes made by others. GitHub provides an intuitive interface and extensive features, such as issue tracking, wikis, pull requests, and code review, improving the software development process.

ℹ️ Synonyms: Source control, Version control, Repository.

How it Works

GitHub operates on the fundamentals of version control and collaboration. When a developer starts a project or wants to contribute to an existing one, they create a repository (commonly known as a repo) to store the project’s files, including code, documentation, and other resources. This repo is accessible to collaborators and can be forked (copied) by others to make changes and submit their contributions via pull requests. The owner of the repository can then review these changes and merge them into the main codebase, maintaining a complete history of revisions and modifications.
