what describes a unitary system?

A unitary system is a form of government where all political power and authority is centralized in a single central government, often with limited power delegated to local governments. In this system, the central government has the ultimate authority to make decisions and govern the entire country, with local governments serving at the discretion of the central government. This system contrasts with federal systems, where power is divided between a central government and multiple regional governments with their own separate powers and responsibilities.
