What is a Jupyter notebook file?
An .ipynb file is a Jupyter notebook: code cells, their results (text, tables, charts) and notes in Markdown, saved as JSON.
The notebook as Jupyter shows it: markdown cells as formatted text, code cells coloured with their In [n] numbers, and their outputs: printed text, tables, charts, error tracebacks. HTML outputs are drawn in a sandbox with scripts off and nothing fetched from the web. The Outputs switch hides them.
