Free Repository and Branch Management Questions and Answers

Question 1

What is a repository in GitHub used for?

Accepted Answer

Storing project files and version history

Answer

A GitHub repository serves as a central location to store all project files, including code, documentation, and assets. Crucially, it also maintains the complete version history of these files, allowing users to track changes, revert to previous states, and collaborate effectively. It's the core unit for project management on GitHub.

Question 2

Which Git command creates a new branch?

Accepted Answer

git branch

Answer

The `git branch ` command is used to create a new branch in your local repository. This command simply creates a new pointer to the current commit, allowing you to switch to this new branch and start making isolated changes. It's the first step in creating a separate line of development.

Question 3

Why are branches useful in Git?

Accepted Answer

They isolate changes for safe development

Answer

Branches are invaluable in Git because they provide an isolated environment for developing new features or fixing bugs without impacting the main codebase. This isolation ensures that experimental or incomplete work doesn't break the stable version of the project. It promotes safe, organized development practices and allows for parallel workstreams.

Question 4

What does `git merge` do?

Accepted Answer

Combines changes from one branch into another

Answer

The `git merge` command integrates changes from a specified branch into your current branch. It combines the commit histories of two branches, creating a new merge commit that incorporates all the changes from both lines of development. This is how features developed in isolation are brought back into the main project.

Question 5

How do you switch to another branch in Git?

Accepted Answer

git checkout

Answer

The `git checkout ` command is used to switch between different branches in your repository. When you check out a branch, your working directory is updated to reflect the files and history of that specific branch. This allows you to work on different features or versions of your project independently.
