On the web page, we have the soon to be familiar Jupyter logo and three tabs:

• Files
• Running
• Clusters

The Files tab lists the objects available to Jupyter. The files used by Jupyter are stored as regular files on your disk. Jupyter provides context managers that know how to process the different types of files and programs you are using. You can see the Jupyter files when you use Windows Explorer to view your file contents (they have an .ipynb file extension). You can see non-Jupyter files listed in the Jupyter window as well.

The Running tab lists the notebooks that have been started. Jupyter keeps track of which notebooks are running. This tab allows you to control which notebooks are running at any time.

The Clusters tab is for environments where several machines are in use for running Jupyter.
