Which network topology is the most common| most popular network topology


Which network topology is most common? this is the most basic question which setting up a network and i am going to answer this question in this article. After reading this article you will have doubt related to most common type of topology used today. So let's begin:

NETWORK TOPOLOGY


The art of connecting computers in a network is known as Topology. A topology refers to both the physical and logical
layout of a network. The physical topology of a network refers to the actual layout of the computer cables and other netwo0rk layout. The logical topology of a network on the other hand, refers to the way in which the network appears to the devices that use it.
There can be following types of the network topology:





 1)  Bus Topology.


   Bus Topology is made up of a main single cable with the terminators at both ends. It is the shared communication medium that makes the backbone of the system. Computer and the other devices including the server are connected to the linear cable for communications. New nodes can be added without halting the network operation. Under this, the messages which are broadcasted ( Clash Of Clans) are carried to the entire network and gets travelled form sender in both directions along the cable.





2)  Ring Topology


   In a Ring Topology, the nodes are connected in a closed loop so that each device is connected to two other devices, one on either side. The computers in a ring topology are connected in the shape of a CLOSED LOOP. Data travels only in one direction in ring. Each computer passes the data to next one on the line automatically.








3)  Star Topology

   In a Star Topology, all the nodes are connected to a central system called switch, which forwards data to the final destination. The switch controls the communication on the network.


4)  Mesh Topology


   The Mesh Topology incorporates a unique network design which enables each computer on the network connects to every other device on the network. The purpose of the mesh design is to provide a high level of redundancy. If one network cable fails, the data always has an alternative path to get its destination.





5)  Tree Topology


  A tree topology combines characteristics of linear, bus and star topologies. It consists of group of star-configured workstations, and enables schools to configure a network to meet their needs.


  

IN THIS WAY WE CAN SAY THAT THE TREE TOPOLOGY IS THE MOST COMMONLY USED NETWORK TOPOLOGY AS IT IS MIXTURE OF SOME COOL TOPOLOGIES.

 

Requirements of a network.


In today’s world networking is the most common thing which helps us to communicate over a long distance via wired or wireless medium.
To set-up Network, devices needed a number of requirements of devices. These requirements for networking must be fulfilled.
So do you know what the basic requirements to set-up a network?
In this article we are going to talk about 10 major requirements which are necessary to set up a network:

SERVER

          A server is a computer that manages the network resources, software and files. It provide functionality to other devices or programs.it is normally dedicated, i.e., it perform no other task besides the allocated task.

                                   

N.I.C

         Each computer on the network must have a Network Interface Card (N.I.C). It is a computer’s gateway to the network via connecting medium, usually a wire or cable, which attaches to the other computer. A Network Interface card is also known as LAN card or Ethernet Card.


 TRANSMISSION CHANNELS

     Each computer in the network is connected through Transmission channels. These channels help exchanging data between two computers in a network.



  HUB

      A hub is a central hardware device in a network that manages traffic across the network. A hub divides the bandwidth or communication speed equally among the computer connected to it.


  SWITCH

       A switch is a central hardware device that manages flow of information among the PCs and devices connected to it. A network cable can only have one data in it at instant so as the data packet comes into switch, its destination address is examined and a direct connection is made between the two computers.




ROUTER

      A Router is a networking device used to connect and facilitate transfer of information between two networks. The router has a micro-computer inside it. This holds a table in memory that contain a list of all the network it is connected to along with the latest information on how each path in the network is, at that moment. This is called Routing Table.


BRIDGE

          A BRIDGE is an electronic device that connects two same types of network and controls the traffic between them. It basically split an overloaded device network into two separate networks for reducing the amount of traffic on each segment and increases the performance of each network.


MODEM

       MODEM stands for Modulator-Demodulator. It is an electronic device that is used to connect a computer to the internet via a telephone or wireless medium. Modem converts outgoing digital data from a computer into analog so that they can be transmitted via telephone line into digital data so that computer could understand and process it.


  REAPTERS

          For long distance trannsmission of data in network, the transmitted signals may get weakened after a certain distance. In such situations Repeaters are used. Repeaters are device which is used to amplify the signals which is being transmitted. It ensures the signal do not get lost over a long distance transmission.



CONNECTORS
       A Connector is a device that joins two computer or networks together when two networks are connected, the entire computer on both the network can exchange the information. Registered Jack 45 is a standard type of connecter that is used for networking cables in a network. These types of connectors are usually connected to a NIC.
