Code Notebook Kernel

Description

A Notebook is a group of Cells. A kernel is a computational engine that executes the code contained in a notebook cell. Each notebook is associated with a kernel of a specific programming language or code transformer which can interpret code and produce a result. For example, a SQL notebook might use a SQLite kernel for running SQL code and an AI Prompt might prepare AI prompts for LLMs.
