Q.What is meant by the tertiary sector of an economy?

The tertiary sector is the part of the economy made up of activities that produce services rather than physical goods.

An economy's activities are conventionally grouped into three sectors based on what is produced. The primary sector draws directly on natural resources (agriculture, mining, fishing). The secondary sector transforms raw material into a finished physical product (manufacturing, construction). The tertiary sector is different from both: it does not produce a physical good at all. Instead, it produces a service — banking, transport, communication, trade, education, health care, tourism, insurance, real estate and public administration are all examples. A service is generally intangible and is consumed at or close to the time it is rendered, unlike a good, which can be stored and transported separately from its production. The tertiary sector today forms the single largest part of India's Gross Value Added.
