Also known as linear busPhysical Bus Topology
-Simplest method of connecting computers
• It is very weakPhysical Bus Topology
All computers are connected via backbonePhysical Bus Topology
Physical Bus Topology
the signal continue
to travel along the cable and through any
connecting device until they weaken enough
to be not detectable anymore or else there is
device that will absorb themsignal propagation
Physical Bus Topology
the signal travel across
the network and if no one receives the it
will continue bouncing back and forth
preventing other computers from
sending datasignal bounce
Physical Bus Topology
a terminator attach
to each end of a cable prevents signals
from bouncing back. The terminator
absorbs all signals that reach clearing
the network to be ready for new
communicationscable termination
Physical Bus Topology
“cable break” it
happens when the backbone is
physically cut or disconnected. When it
happens no termination will happen
keeping the signal to bounce halting all
network activity.cable failure
One of the benefit of _is that it inherent
centralization of resourcesPHYSICAL STAR TOPOLOGY
computer is located in one
location it needs more cable
installationPHYSICAL STAR TOPOLOGY
connected by cable segment to
a central devicePHYSICAL STAR TOPOLOGY
Computers are connected to a central device
Requires more cable for installationPhysical ring topology
If central device will fail the network activity
will halt
If one device fail network activity is not
affected unless the fail device is responsible for network activityPhysical ring topology
Each computer connects directly to the next
computer
The cable forms a circle of all connected devicesPhysical ring topology
Termination is not required
Every computer is responsible for retransmitting
the dataPhysical ring topology
Reasons of adapting physical star topology
1. Problem of troubleshooting and
managing a physical bus and ring
network
2. Because of the single cable failureok
