How Can a Single Computer Run So Many Apps at Once?

A computer is like a chef who can cook several dishes at the same time. Imagine you're eating pizza, listening to music, and typing a message all at once, that’s like having multiple chefs working in the kitchen without getting confused. The computer uses something called memory to keep track of what each app is doing so it doesn’t forget where it left off when switching from one task to another. It also has a special part called the CPU that takes turns helping each app finish its job, just like the chef helping with each dish in order.
