Git and GitHub Mastery

What is a version control system and why is it important in software development?

• A version control system is used to store passwords securely

• A version control system is important in software development to track changes, facilitate collaboration, track bugs, and revert to previous versions.

• Version control systems are not useful for tracking changes in code

• Version control systems are only important for large software projects

Explain the difference between Git and GitHub.

• Git is a version control system, while GitHub is a platform for hosting Git repositories.

• GitHub is a version control system, while Git is a platform for hosting Git repositories.

• Git and GitHub are the same thing.

• Git is a platform for hosting Git repositories, while GitHub is a version control system.

List three common Git commands used for version control.

• git add, git commit, git push

• git pull

• git merge

• git status

How do you create a new repository on GitHub?

• Log in to GitHub, click on 'Explore', select 'New project', fill in details, and click 'Start project'

• Log in to GitHub, click on '+', select 'New repository', fill in details, and click 'Create repository'.

• Go to GitHub, click on 'Settings', select 'New repository', fill in details, and click 'Save'

• Log in to GitHub, click on 'Profile', select 'Create repository', fill in details, and click 'Submit'

What is branching in Git and why is it useful?

• Branching in Git is only useful for individual developers and not for teams

• Branching in Git is a feature that slows down the development process

• Branching in Git is the process of merging all changes into the main branch

• Branching in Git is the ability to diverge from the main development line to work on different features or fixes independently, keeping changes isolated and enabling collaboration without interfering with the main codebase.

Explain the difference between 'git merge' and 'git rebase'.

• git merge deletes the branch after integration, while git rebase keeps the branch intact

• git merge reverts changes, while git rebase integrates changes

• git merge moves the entire branch to the tip of another branch, while git rebase creates a new commit

• git merge integrates changes by creating a new commit, while git rebase moves the entire branch to the tip of another branch.

How can multiple developers collaborate on a single Git repository?

• By sending emails with code snippets

• By using branches, committing changes, pulling and pushing code, resolving conflicts, and reviewing code through pull requests.

• By using carrier pigeons to deliver code changes

• By writing code on paper and mailing it to each other

What is a pull request in GitHub and how does it facilitate collaboration?

• A pull request in GitHub is a way to delete files from a repository and facilitates collaboration by causing confusion and errors.

• A pull request in GitHub is a way to propose changes to a repository and facilitates collaboration by allowing for review, discussion, and eventual merging of changes.

• A pull request in GitHub is a way to ignore changes in a repository and facilitates collaboration by hindering progress and communication.

• A pull request in GitHub is a way to copy code from a repository and facilitates collaboration by introducing bugs and conflicts.

Describe the typical Git workflow for a team project.

• Clone, commit, push, pull request, review, merge, pull

• Fork, commit, push, pull request, review, merge, pull

• Clone, branch, commit, push, review, merge, pull

• Clone, branch, commit, push, pull request, review, merge, pull

What are some best practices for using Git in a team environment?

• Implement a branching strategy, use pull requests, regularly pull changes, utilize Git hooks, and maintain good communication.

• Never pull changes from the repository

• Use Git hooks excessively

• Avoid using branches
