What is the difference between concurrency and parallelism?

What is the difference between concurrency and parallelism?

Concurrency is about dealing with multiple tasks at once, while parallelism is about executing multiple tasks simultaneously.

Can you give me an example of concurrency?

Sure! Imagine a chef preparing a meal. They can chop vegetables, boil water, and grill meat at the same time, but not all tasks are done simultaneously.

And what about parallelism?

In parallelism, think of multiple chefs working on different dishes at the same time in a kitchen. Each chef is focused on their own task.

How do these concepts apply in programming?

In programming, concurrency allows multiple tasks to make progress without waiting for each other, while parallelism uses multiple processors to execute tasks simultaneously.
