Concurrent vs. parallel execution

“

- Just because a program is structured to have multiple threads or processes does not mean they'll necessarily execute in parallel. A concept that's closely related to parallel execution, but often gets confused with it, is concurrency. Concurrency refers to the ability of an algorithm or program to be broken into different parts that can be executed out of order or partially out of order without affecting the end result. Concurrency is about how a program is structured and the composition of independently executing processes. Consider this recipe to make a salad, which includes several steps that slicing and chopping vegetables. We can decompose those steps into a collection of concurrent tasks because the relative order in which we do them doesn't matter they're order independent. To keep things simple, let's just focus on two of those tasks for now. I'll chop onions. - And now slice cucumbers. This knife represents our computer's processor. We only have one knife, so this is a…
