Uses a dual ring of single-mode or multimode fiber-optic.
Type your answer here... FDDI
Physical Address
Both Token Ring and FDDI use the concept of a ring topology structure. However, Token Ring is used in a LAN, and FDDI is used in a MAN.Token Ring is implemented with copper cable (UTP cable) and FDDI uses Fiber Optic cable.Finally, the protocols are very different between the two. FDDI uses a synchronous type of transmission, where Token Ring uses an actual token (a 3 character packet) to control who has access to transmit or receive on the network. FDDI does not use this technique.
PHYSICAL....AT DEMODULATION, HENCE IT is always done at the physical layer....usually some type of control system engineering is used... using a maximum likelihood estimation or some type of apriori estimation
The OSI model is a general model for networking . It has seven layer in total and each layer have some responsibilities. The layer that determines the communication mode is physical layer.
There are seven type of OSI reference model:-Layer 7: The application layer Layer 6: The presentation layer Layer 5: The session layer Layer 4: The transport layer Layer 3: The network layerLayer 2: The data-link layer Layer 1: The physical layer
A SONET is a type of network technology layer that is physical. It is used for transporting a lot of traffic over fiber optic cabling.
It required physical energy from the rider paddling and transform to kinetic energy.
It is a metal that contains a significant amount of iron. Without protective layer it will form oxides and rust. Carbon steel is a good example. Stainless steels contain Chromium that automatically provides the protective layer.
The ozone layer does not affect anything. It is a protective layer.
The Asthenosphere is a layer of the upper mantle.
