the Token Ring system?
A device that manages the Token ring hub
passing of the token instead of
relying on individual computers
to pass it.
How does the token ring hub It improves the reliability of the network.

Topology whereas the Bus topology
computers share the media or
coaxial cable for data
transmission.
The coaxial cable that is looped ThinNet
through each networking device
to transmit data in a bus
topology
In this topology, all devices on Bus topology
the network can see each
other's data traffic.
Topology whereas each Bus topology
computer must wait for pauses
in transmission or until the
transmission from one device is
complete before initiating a new
transmission onto the network.

bus topology? 2. The use of the shared coaxial cable prevents data transmission
from being very bandwidth-efficient."
Which topology is seldomly Bus topology
used in modern networks?
What is the most common Star topology
topology used in today's LANs?
Topology that uses twisted-pair Star topology
cables with modular plugs to
connect computers and other
networking devices.
Topology whereas each device Star
is connected to a switch or hub
A switch or hub facilitates the star
transfer of data between
networking devices in this
topology
Transmits data to all the devices hub
connected in the star network
Also called a multiport repeater hub
