❓ Frequently Asked Questions
What is version control and why is it useful?
Version control is a system for tracking changes to files over time. It keeps a complete history, allows you to revert to earlier states, and makes collaboration safer and easier.
What is Git and what does distributed version control mean?
Git is a popular version control system. Distributed version control means every clone has the full project history, enabling offline work and flexible collaboration.
In Git, what are a repository, a commit, and a branch?
A repository stores the project history. A commit is a saved snapshot of changes, and a branch is a parallel line of development that can be merged back later.
What is the difference between the staging area and a commit?
Staging (git add) marks changes to include in the next commit; committing records those staged changes as a new snapshot.
How do you share work with your team using Git?
Push your commits to a remote repository to share them, and pull (or fetch) to incorporate others’ changes. Branches and pull requests help manage collaboration.
