3. What is difference between Git fetch and Git pull code example

Example 1: git fetch vs pull

Git Fetch ==>The Git Fetch command 
downloads commits, files from a remote
repository into your local repo. 
Fetching is what you do when you want
to see what everybody else has been working on

Git Pull ==> fetch and merge any 
commits from the remote branch

Example 2: git pull or fetch difference

git fetch is the command that tells your local git to retrieve the latest meta-data info from the original (yet doesn’t do any file transferring. It’s more like just checking to see if there are any changes available).

git pull on the other hand does that AND brings (copy) those changes from the remote repository.
