The document provides definitions for a service and a product. A service is defined as the situation where a provider furnishes something to meet a customer's needs or wants, which may involve physical products, intangible aspects, or a combination, and is delivered through human interaction. A product is defined as anything that is the output of a production process, intended to be sold in the market for profit, and can be stored, repaired, and resold upon purchase and transfer of ownership. Tourism involves both services and products, as it entails the provision of destinations, accommodations, transportation, and activities by suppliers to travelers seeking experiences.
