Technology services


The quaternary sector of the economy is a way to describe a knowledge-basedpart of the economy - which typically includes services such as information technology, information-generation and -sharing, media, and research and development, as well as knowledge-based services like consultation, education, financial planning, blogging, and designing.

The quaternary sector is based on knowledge and skill. It consists of intellectual industries providing information services, such as computing and ICT (information and communication technologies), consultancy (offering advice to businesses) and R&D (research, particularly in scientific fields). According to some definitions, the quaternary sector includes other pure services, such as the entertainment industry, and the term has been used to describe media, culture, and government.

"Quaternary sector" is a further delineation of the three-sector hypothesis of industry in the sense that the quaternary sector refers to a part of the third or tertiary sector along with the quinary economic sector. It has been argued that intellectual services is distinct enough to warrant a separate sector and not be considered merely as a part of the tertiary sector. This sector evolves in well-developed countries and requires a highly educated workforce.
