Notebook Server: The backend process that serves the Jupyter Notebook interface to the user. In a single-user setup, this server runs locally; in a JupyterHub deployment, each user gets an isolated notebook server instance managed by the Spawner and Proxy components.
Image: A pre-configured software environment, used in EOSC EU Node's containerized deployment with Kubernetes. An image defines the base software, dependencies, and configurations required for a Jupyter Notebook server. JupyterHub can use different images to provide users with specific environments tailored to their needs.
