Question: Examine does C-SCAN look to survive? ADD ONS

Case: Routing calculations can be either interface state or distance-vector. Characterize these two terms and make sense of the compromises between them. [5 marks] (2.i) You are expected to plan a geography revelation convention for an organization of exchanging hubs interconnected by joins. There are n hubs, l connections, the greatest level of any hub is k and there is a way between any two hubs of not more than d bounces. All connections are bi-directional. Every hub has a remarkable identifier of four bytes which it knows. The advantage of polygon scan conversion is that it is fast. Polygon scan conversion algorithms are used in computer games, flight simulators, and other applications where interactivity is important. To give a human the illusion that they are interacting with a 3D model in real time, you need to present the human with animation running at 120 frames per second or faster for passive viewing on a monitor, TV, or movie screen.
