  It depends what the computer code does. If I’m writing code to solve a small equation and draw it on a graph then any old computer will do.
  However if I’m writing code that does loads of things and calculates an equation hundreds of thousands of times, then I need quite a fast computer.
  
  Some of the code I’ve needed to run on a computer I have started one day, I went on holiday for a week, came back and it still hadn’t finished. Those are times when you need a supercomputer. But sadly I don’t have one.
