Concurrent computing

Concurrent computing is a way of running different parts of a program or task at the same time. It's like having a lot of different people working on the same task all at once. For example, if you have a long list of things to do, instead of waiting for one person to finish the whole list, you could get a group of people to all work on different things at the same time. This way, you can finish the work faster!
