ELI5: Explain Like I'm 5

parallel programming

Parallel programming is like taking a big job and breaking it down into smaller chunks so that different parts of the task can be done at the same time. Imagine you wanted to bake a cake - you would have to do all the steps in order, like mixing the ingredients, baking the cake, and icing it. With parallel programming, you could get lots of people to help with the job. So one person could mix the ingredients, another could bake the cake, and a third could ice the cake at the same time. This way the job gets done faster since multiple people are working on it together.
