Complete Git Guide: Understand and Master Git and GitHub - Fetching Remote Changes Manually

This video tutorial covers the process of performing a fast forward merge in Git, making changes in both local and remote repositories, and understanding the differences between them. It demonstrates how to use Visual Studio Code for local changes, create new files in a remote repository, and compare commits. The tutorial also explains how to fetch changes from a remote repository, examine Git objects, and understand different Git object types, such as BLOBs and tree objects.

What is a fast-forward merge in Git?

• A merge that creates a new commit to combine changes.

• A merge that requires resolving conflicts between branches.

• A merge where the local branch pointer is moved to match the remote branch without conflicts.

• A merge that deletes the local branch after merging.

What is the purpose of making changes in both local and remote repositories before a Git pull?

• To automatically synchronize both repositories without manual intervention.

• To avoid any need for merging changes.

• To simulate a real-world scenario where changes occur in both locations.

• To ensure that the local repository is always ahead of the remote.

What does the 'git fetch' command do?

• It pushes local changes to the remote repository.

• It deletes outdated branches from the local repository.

• It updates the local repository with changes from the remote without merging.

• It merges changes from the remote repository into the local branch.

After performing a 'git fetch', what is the state of the local repository?

• The local repository is fully synchronized with the remote.

• The local repository has all remote changes but they are not merged.

• The local repository is behind the remote repository.

• The local repository is ahead of the remote repository.

What is the significance of the Git objects folder?

• It holds the actual data of commits, trees, and blobs.

• It is used to store temporary files during a merge.

• It contains the configuration files for Git.

• It stores all the branches in the repository.

How does Git ensure that the local repository has the same objects as the remote after a fetch?

• By creating new branches in the local repository.

• By automatically creating all missing objects in the local repository.

• By deleting outdated objects in the local repository.

• By merging all changes immediately after fetching.

What is the next step after fetching changes from a remote repository?

• Deleting the local branch to avoid conflicts.

• Creating a new branch to test the changes.

• Merging the fetched changes into the local branch.

• Immediately pushing changes to the remote repository.
