Network topology

 

                        Network Topology


What is topology-:  Topology define the structure of the network of how all the components  are interconnected to each other they are two type of topology physical and logical topology.  


               Types of topology

  


1.Bus topology-:The bus topology is designed in such a way that all stations are connected through a single cable known as backbone cable. Each node is either connected to the backbone cable by drop cable or directly connected to the backbone cable. when a node wants to send a massage over the network it put a massage over the network. all the stations available in the network will received the massage whether it has been address or no.

 



2.Ring topology-:The node that received the message from the previous computer will retransmit to the next node .the data flow in one direction ,each computer are connected two computer.



3.Star topology-: every node are connected to the central computer or central hub, switch star topology is most popular topology in the network implementation. it  cost is high . 

coaxial cable and rj45 cables are used to connected computers. 




4.Mesh topology-: Each computer are connected to another computer ,there are multiple path from one computer to another computer, the internet is an example of mesh topology.




5.Tree topology-:Tree topology is the combination of bus topology and star topology .




6.Hybrid topology-: The combination of different different networks, also known as hybrid topology. A hybrid topology is a connection between different links and node transfer the data. 

ex-: Mesh + Tree + Bus + Star = Hybrid

                                              Network What is network-:   It is group of computer linked to each other that enable the computers to communicate with another computer and share their resource data.                                      1.PAN-: It is use for connection device of personal use also kwon as pan it is range of 10 meter.                   2.LAN-: It full form is (Local area network) i t is group of computer connected to each other in a small area such as building  office ,it is use for communicate two or more it is range of 100-1500m the data is transfer at extremely  faster rate it providing higher security and computer through a communication medium s...

      Networking devices 1.Nic card -: it  is pre install in our computer/system , we are connected to the internet with the help of NIC card it's full form is (Network interface card ) they are provide unique id on internet also called as mac address (Media access control). Ex-:   10:c4:d4 : 3a:6f:5e note(first three latter manufacture id and last three latter unique id )   2. Router-:  Router is a network device which work as a traffic controller , a main work of router is to chose a free traffic path through which the data packet will travel router receive data packet to the sender analyse and forward the data packet than giving to receiver               Advantage of Router                         1. he provide connection between two different network.       2. Transmission rate is very high.     3.he provi...
