What is one fundamental difference between distance vector routing protocols and link state routing protocols?
Distance vector protocols exchange their routing tables, and add a metric to each route. Link-state routing protols exchange topology information, then calculate the routes. As a result, there are the following fundamental differences:
- The information that is exchanged - routing table vs. topology information.
- Link-state protocols know the topology of the network (or an area); distance vector routing protocols don't.
- When the best route is calculated: in distance-vector routing protocols, a metric is added while the route is propagated from router to router. In link-state protocols, the best route is calculated separately by each router, only after having complete topology information.
The fundamental units are based on specific standards for each unit. Derived units result from manipulating the fundamental units. For example, the SI unit for distance or length is the meter, and the SI unit for time is the second. If you divide meters by seconds, you get m/s, a derived unit for speed or velocity.
What is the fundamental difference between a health and safety representative and a representative of employees safety?
I removed the faceious answer by ID0772977175 and substituted the following: Guessing you mean, "What is the difference between elements and compounds" Elements are fundamental substances that cannot be broken down into or reduced to simpler substances. Compounds are made up of elements and can be reduced to these fundamental elements.
Fundamental niche is the natural habitat of a species, where it can easily get food for its energy requirements, and can mate and reproduce without the fear of predators Realized niche is the environment that a species finally gets because of many limiting factors Read more: http://www.differencebetween.com/difference-between-fundamental-and-vs-realized-niche/#ixzz2DcWgiYIl
