A type of topology that gives a virtual representation of all the nodes connected in the network. I mean this topology explains how data is transferred in the network. For example, it explains how data move from switches and routers.
There are two types of logical topology:-
In a bus topology, all the nodes are connected to a central bus. All computers or nodes have the same level of authority to transfer data. In a bus topology, the data moves in half-duplex mode i.e. data is either received or transfer at a time. The data moves in one direction at a time.
Ring topology is also a type of logical topology. In-ring topology the computers are connected in a ring shape i.e. first computer is connected to the second computer and the second computer is connected to the first computer and third computer. The last computer is connected to the first computer and hence it makes a ring shape. If any data is to be moved from the first computer to the third computer then the first data moves to the second computer and then the second computer finally moves the data to the third computer. The computer with a token has permission to send the data. By using a token the collision of data is prevented in the network.
