What are the different names of coffee and how do they differ in taste and preparation methods?

Coffee is known by various names such as espresso, latte, cappuccino, and americano. These differ in taste and preparation methods based on the ratio of coffee to milk or water, the type of milk used, and the addition of foam or flavorings. Espresso is strong and concentrated, while latte and cappuccino are creamier with varying levels of foam. Americano is made by diluting espresso with hot water for a milder taste.
