What is Concurrency?

Concurrency is when multiple things can happen at the same time, like a team working together on different parts of a puzzle.

Imagine you and your friend are both building sandcastles at the beach. Instead of taking turns digging or stacking sand, you both do your own work at the same time, one of you makes a tower, while the other creates a moat. This is concurrency in action: two people working on different parts of the same project without waiting for each other.

Think of a restaurant kitchen. One cook is chopping vegetables, another is stirring a soup, and a third is baking cookies. They're all doing their own jobs at the same time, this is concurrency in real life. Each cook can work on their task without holding up the others.

If one cook had to wait for the other to finish before starting their job, that would be like one thing happening at a time, not concurrency. But with concurrency, everything gets done faster and more efficiently, just like your sandcastles or that delicious soup!
