The service sector is a part of the economy that provides services rather than goods. This includes industries such as healthcare, education, finance, and hospitality. Unlike manufacturing, which produces tangible products, the service sector focuses on delivering experiences, expertise, and support to individuals and businesses. Services in this sector can be categorized into various types, including personal services, professional services, and public services. Examples include doctors providing medical care, teachers delivering education, and bankers offering financial advice. The service sector plays a crucial role in economic growth and employment, often representing a significant portion of a country's GDP.
