Which type of routing protocol uses the same algorithm as a car navigation system?

The correct answer is link-state protocols. Link-state routing protocols operate using a method similar to that of a car navigation system, which constantly assesses and updates the best routes based on real-time conditions. These protocols maintain a complete view of the network topology by having each router construct a map of the network. Routers periodically send updates indicating their links to other routers and their statuses, enabling all routers to have a consistent and updated view of the entire network. This allows them to calculate the shortest path to a destination based on the most current information.

In a car navigation system, similarly, real-time traffic data is utilized to determine the fastest or most efficient route available, adapting continuously as conditions change.

Distance-vector protocols, on the other hand, work by passing information about distances and direction to nearby routers but do not have a complete view of the network topology. Hybrid protocols combine aspects of both distance-vector and link-state routing but do not fully align with the functionality of a car navigation system. Static routing involves manually setting routes and does not adapt to changes in the network, unlike link-state protocols.
