The command "jupyter notebook" launches the Jupyter Notebook application, which is an open-source web-based interactive computing environment.

When you run this command in a command line interface or terminal, a web browser window will open, displaying the Jupyter Notebook dashboard. This allows you to create, open, and edit Jupyter notebooks (.ipynb files) that contain live code, equations, visualizations, and explanatory text.

Once you have the Jupyter Notebook dashboard open, you can create a new notebook by clicking on the "New" button and selecting a programming language kernel (e.g., Python, R, Julia). Notebooks provide an interactive environment where you can write and execute code cells, view the output, and save the results for future reference. It also supports markdown cells for adding text, images, and equations in a rich-text format.

Jupyter Notebook is widely used in data science and analysis, machine learning, scientific research, and teaching due to its flexibility, interactivity, and ability to combine code, visualizations, and documentation in a single environment.
