network topologies
bus topolgy
it is the simplest network topology.it consist of single central cable known as bus.all the devices are connected to the bus along its length to communicate with each other.
-
disadvantages
if bus is damaged at any point,the entire network stops working
-
ring topology
it is shaped just like a ring.it is like a bus with both ends connected together.all the messages travel in same direction .
-
disadvantage
if ring is broken at one point,the entire network stops functioning
-
-
star topology
in star topology all the nodes are connected to a central devices called switch or hub .a switch can bo connected to another switch to expand the network
-
-
mesh topology
in mesh topology all the network nodes are connected to all other nodes.messages sent on a mesh network,can take any possible path from source to destination.
