Analogy

Imagine you are moving to a new house. You have three options for transporting your belongings: using a truck, a train, or a conveyor belt. The truck offers flexibility and mobility, allowing you to quickly load and unload your items. The train, on the other hand, can carry a large quantity of items over long distances, but it is less flexible. The conveyor belt offers continuous and automated transportation, making it suitable for heavy and bulk items. Each option has its advantages and disadvantages, and choosing the right method depends on your specific needs and requirements.
