Which of the following is true?
|
|
In a ring network there are no collisions because data packets travel only in one direction
|
|
|
In a bus network there are no collisions because data packets travel only in one direction
|
|
|
In a ring network there are no collisions because data packets travel on different cables
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -"Rings prevent collisions.” The term “ring” only refers to the layout of the cables. It is true that there are no collisions on an IBM Token Ring, but this is because of the layer 2 Media Access Control method, not the physical topology (which again is a star, not a ring.) Token passing, not rings, prevent collisions.
Detailed explanation-2: -In a ring topology, chances of collision is reduced because the traffic flows in only one direction. In a bus topology, any computer that is connected to a network will be able to see all the data transmissions on all the other computers. So there are no chances of security.
