A module is like a Lego block. Imagine you have a big box of Lego blocks, and each block has a special job. One block might be a wheel, another might be a door, and another might be a window. When you put these blocks together, you can build something amazing, like a car or a house. In the same way, a module is a piece of a bigger project. It has its own job, and when you connect it with other modules, you can create something really cool, like a computer program or a toy.

Think of a module as a chapter in a storybook. Each chapter tells a part of the story, and together, they make the whole book. You can read one chapter at a time and understand a little part of the story, but when you put all the chapters together, you get the whole adventure. A module is like one of those chapters, helping to tell the story of a bigger project.

Consider a module as a piece of a puzzle. Each puzzle piece has a unique shape and place. On its own, it doesn’t show much, but when you fit it with other pieces, the picture becomes clear. A module works the same way, fitting into a bigger system to help complete the whole picture.
