basic network topologies:

Ring topology-

connects of every one nodes, para ang signals ay hindi potol potol..in which each node connects to exactly two other nodes, forming a
circular pathway for signals, attached to the ring networks overcome this by sending data on a clockwise and a counterclockwise ring.


Mesh topology-


route data,and allows for continous connection to reconfiguration.from to node to node until the destination is reached.mesh networked differ from other networks in that component parts ay naka connect lahat sa isat isa.


Star topology-


isa sa mga common computer network topologies,it is consists of one central switch, hub or computer to trasfer the messages,the advantages,.. is Better performance,
Benefits from centralization..., it is easy to understand.


Bus topology-


is a network architecture in which a set of clients are connected via a shared communication line, there are several common instance of the bus architecture, including one in the motherboard of most computers, and those in some versions of Ethernet networks. the computers on the bus simply listen for a signal; they are not responsible for moving the signal along.


Tree topology-

consists of star-configured nodes connected to switches/concentrators, each connected to a linear bus backbone.sometimes including the originating node
lahat ng mga peripheral nodes ay maka communicate with all others by transmitting to.. and receiving from, the node only.The failure of a transmission line linking any peripheral node to the central node will result in the isolation of that peripheral node from all others, but the rest of the systems will be unaffected.
