Network Physical Topologies
Star Topologies
Characteristics
every node has its own dedicated connection to the hub.
hub acts as a repeater for data flow
can be used with twisted pair, optical fibre or coaxial cable
Advantages
It is high-performing as no data collisions can occur
It is very reliable because if one cable or device fails then all the others will still work.
Less expensive because each device only need one I/O port and wishes to be connected with hub with one link
Disadvantages
If the connecting network device (network switch) fails, nodes attached are disabled and can’t participate in network communication.
More expensive than linear bus topology due to the value of the connecting devices (network switches)
Requires more cable than a linear bus .
Extended Star Topologies
Characteristics
The new devices can be easily added to the network and can connect to the central hub. Similarly, the nodes can be easily removed from the network.
The network maintenance and monitoring can be done properly
Advantages
This topology helps to control multiple nodes at the same time
It is very reliable – if one cable or device fails then all the others will still work
It is high-performing as no data collisions can occur
Disadvantages
if the central hub goes down it will lead to whole network failure
Bus Topologies
Characteristics
all nodes or devices are linked with one transmitter or server computer via a single cable (mostly coaxial cable) called backbone.
All computers in the network are connected via a single cable as a transmission medium
Each end of the main cable has a terminator attached to stop the signal and prevent signal collisions
Advantages
The failure of one station does not affect the rest of the network.
It is cheaper than other network options. ...
It is easy to connect a device to the network. ...
Disadvantages
if the main cable fails or gets damaged the whole network will fail.
as more workstations are connected the performance of the network will become slower because of data collisions.
every workstation on the network "sees" all of the data on the network – this is a security risk.
Mesh Topologies
Characteristic
It is fault tolerant because of redundant connections.
It works best for networks with a large number of nodes.
A mesh topology provides redundant links across the network.
Advantages
messages can be received more quickly if the route to the intended recipient is short
messages should always get through as they have many possible routes on which to travel
multiple connections mean (in theory) that no node should be isolated
Disadvantages
full mesh networks can be impractical to set up because of the high number of connections needed.
many connections require a lot of maintenance.
