How the tertiary sector differs from quaternary and quinary sectors?

The tertiary sector is also known as the service sector, and it mainly provides services instead of goods. This includes activities like banking, transportation, retail, education, tourism, and healthcare. It supports the primary (farming, mining) and secondary (manufacturing) sectors by offering essential services such as distribution, communication, and trade.

On the other hand, the quaternary sector focuses on knowledge-based activities such as research, information technology, data analysis, and scientific development. It deals with creating and sharing information rather than physical products.

The quinary sector is the highest level, involving decision-making and leadership roles in government, education, healthcare, and business. Examples include CEOs, policymakers, scientists, and top government officials.
