Questions & Answers

Q: What is Git and why is it important?

Git is a free and open-source version control system used to track and manage code changes. It is important for developers as it allows them to collaborate on projects, track changes, and revert to previous versions if needed.

Q: What is the difference between Git and GitHub?

Git is the tool used for version control, while GitHub is a web-based platform that hosts Git repositories. GitHub allows for easy collaboration, code sharing, and project management with features like pull requests, issue tracking, and project boards.

Q: How are Git branches used in software development?

Git branches allow developers to work on separate features or bug fixes without affecting the main codebase. Branches can be merged back into the main branch (usually called master) when the changes are complete and reviewed.

Q: How can I undo commits or changes in Git?

Git provides commands like "git reset" to undo commits and "git checkout" to discard changes made to files. However, it is important to use these commands with care as they can modify the commit history and potentially cause data loss.

Q: What is the purpose of forking a repository on GitHub?

Forking a repository on GitHub creates a copy of the original repository under your own account. This allows you to freely make changes to the code without affecting the original project. Forking is commonly used for contributing to open-source projects or creating personal copies of existing projects.
