What is topology?
Topology refers to physical and logical network layout.Network's physical topology is the actual layout to cables and networks devices.Logical topology refers to the way in which the network appears to the devices that use it.
What is the common network's topology?
There are a lot of topology like :
- Bus topology
- Ring topology
- Star topology
- Wire Mesh topology
What is Bus topology?
It uses a backbone cable to connect all the computers used in the network.
Bus topology has a lot of advantages like:
- Compared to other topology , it is cheap and easy to implement.
- It uses less cable than other topology.
- Don't use specialized network equipment.
- Network disruption might occur when computers are added or removed.
- A break in the backbone prevents all computers from accessing the network.
What is Ring topology?
In ring topology, the data travels in a circular from one computer to another.
There are some of its advantages :
- Easy to implement
- Don't need a network equipment
- Any break in any cable causes network disruption.
- If a single system fails the whole network fails.
What is Star topology?
In star topology, all the networks devices connect to a central device called switch.
- Easy to implement
- Cable failure affects only a single user.
- Require a network equipment.
- Its cost is higher than bus and ring topology.
What is Mesh topology?
In mesh topology,any computer on network connects to every other.It creates a point to point connection between every network.
- A network can be expanded without disruption.
There are some disadvantages for mesh topology like:
- Hard to implement
- Use more cable than other topology.
