Topology

Topology:- It is the arrangement with which computer and network devices are connected to each other."Arrangement layout can be actual and logical".

  



Bus:- It is uses a trunk or backbone to which all of the computers on the network connected.Cable segment must end with a terminated.
Thick Ethernet (10base5) used for backbone
Advantage:-
1)Cheap and easy to implement
2)Require less cable
3)Work well for small network
Disadvantage:- 
1)Network disruption when computers are added and removed
2)A break backbone whole system down.
3)Sharing some cable slow response.




Ring:- Computer connected in a closed group.In ring topology no beginning and end,All device have equal access to medium.Most common type is taken ring.

Advantage:-
1)Data travel at great speed
2)No collision
3)No terminated require
Disadvantage:-
1)Require more cable than bus
2)A break in ring will bring will down.
3)Not as common as bus




Star:-All computers/devices connected to central devices (hub and switch). Each devices require a single cable.Point to point connection between device and hub.






Mesh:-Each node connected to every other,most often used in WAN to interconnected LAN.

Advantage:-
1)Improve more tolerance can carry more data. 
Disadvantage:-
1)Expansive , difficult to install.



Hybrid:-
