Construction is the process of constructing a building or infrastructure.

Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client.

Construction as an industry comprises six to nine percent of the gross domestic product of developed countries.

A technology demonstration or Demonstrator model is a prototype, rough example or an otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology.

They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users.

Industry is the production of goods or related services within an economy.

The major source of revenue of a group or company is the indicator of its relevant industry.

When a large group has multiple sources of revenue generation, it is considered to be working in different industries.

Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and feudal economies.

This came through many successive rapid advances in technology, such as the production of steel and coal.

The public sector is the part of the economy concerned with providing various governmental services.

The composition of the public sector varies by country, but in most countries the public sector includes such services as the military, police, infrastructure (public roads, bridges, tunnels, water supply, sewers, electrical grids, telecommunications, etc), public transit, public education, along with health care and those working for the government itself, such as elected officials.

The public sector might provide services that a non-payer cannot be excluded from (such as street lighting), services which benefit all of society rather than just the individual who uses the service.

The private sector is the part of the economy, sometimes referred to as the citizen sector, which is run by private individuals or groups, usually as a means of enterprise for profit, and is not controlled by the State (areas of the economy controlled by the state being referred to as the public sector).
