git pull and git fetch are both used to retrieve changes from a remote Git repository, but they have some differences.

git fetch retrieves the latest changes from the remote repository, but it doesn't merge those changes into your local branch. Instead, it updates your local copy of the remote branch so that you can inspect it and decide if you want to merge it with your local branch later.

On the other hand,  git pull combines two commands: git fetch and git merge. It fetches the latest changes from the remote repository and immediately merges them into your local branch. This means that git pull will automatically merge the changes from the remote repository into your local branch without giving you a chance to review them first.

In summary, git fetch is a safer option if you want to inspect the changes before merging them into your local branch, while git pull is a quicker option if you're confident that you want to merge the changes immediately.
