title: What is a kernel in Jupyter Notebook and how it is different/similar to actual kernel (related to Operating System)?
body: <p>I hear and see a lot of this word "kernel" as I'm using Jupyter Notebook a bit. I just want to know what "kernel" represents in Jupyter Notebook. Is it the same meaning that we use in Operating System? If it is similar/different, how exactly?</p>
  
  <p>Do both kernels do the hardware interaction?</p>
