Cooperative multitasking is a way of allowing multiple programs to run at the same time on a computer. Imagine that you have a group of people working on a big project together. Each person is responsible for a different part of the project. Cooperative multitasking works like this: each person takes turns working on their part of the project, so that the whole project can get done faster. On a computer, cooperative multitasking means that multiple programs can work together to get things done, like having two people work on two different parts of the same project at once. This can help the computer work faster, because it doesn't have to take turns with each program.
