Hi Carl,

The basics of it are as follows, a little simplified to hopefully make it clear

Git uses a working directory that contains the files which you are working on. These get converted into a snapshot when you commit, and these commits form the history of your project. These snapshots along with everything else that git needs to work are stored in the git directory, often called ".git".

When you zip the files you are working on you are creating a manual snapshot of your project. If you zip the git directory you are compressing the entire git repository and this has enough information to recreate your entire history. If you zip both of them you get your history as well as any changes that have not been committed yet. When a server holds a copy of your repository it will not include a working directory at all, but instead just the git directory. In this situation the git directory will often be called the same name as the project.

The zip from GitHub does indeed only contain the working directory, and so doesn't include the history.

Hope that helps!
