Computer Networking Tutorial For Beginners in English

What Is a Network?

The network is a connected collection of devices that can communicate with each other. Networks carry data in many kinds of environments, including homes, small businesses, and large enterprises.(Network is a collection of the different components to share data and hardware resources)

        

ABOUT COMPUTER NETWORKING TUTORIAL















Common Physical Components of a Network  
     There is four type of physical components in a computer network.The computer, interconnections, switches, and routers.The major resources that are shared in a computer network include backup devices, data and applications, peripherals, storage devices, and.The most common network user applications include e-mail, web browsers, instant messaging, collaboration, and databases.

What Is Networking?

       Networking means the way to configure a network or the way in which we can share data and hardware resources.

There are 2 components of  networking:-
(a) Topology
(b) Networking Model

(a) Topology means -
            Ii means physical structure of a network.

There are different types of typologies:-

Point to Point  or  Peer to Peer Topology

         It means 2 computers are directly connected.

Features :-
                Maximum  10  computers are recommended
                No fault tolerance or no redundancy

                Speed is slow.

 Bus Topology



It means all the computers are connected to a single bus or single cable.
Features :-
        Maximum  10 computers are recommended
        It has fault tolerance
        Speed is slow
        BNC-T connectors (British Naval Connector)    
        Coaxial Cable
        Terminators are used at both ends to absorb the waste signals and to stop collision by providing CSMA/CD (Carrier Sense Multiple Access / Collision Detection).

Ring Topology

        It means computers are connected in the shape of a ring or in circular design and signals will be flowing in the same direction, it can be clockwise or anti-clockwise.
Features :-
        Maximum  10  computers are recommended
        No fault tolerance
        Speed is fast as compared to Bus and Point to Point topology because the token will be generated and create a session.

Mesh Topology

        It means all computers are connected directly with each other.
Features :-
                Speed is fast
                It has fault tolerance
                No limit for number of computers
                It is costly or complex

Star Topology

            It means all computers are connected with centralizing devices like hub or switch.
Features :-
                No limit of number of computers
                Speed is very fast
                It has better fault tolerance
                Easy installation, easy maintenance, and easy troubleshooting.

 Star-Plus  or Extended Star Topology:

        It means more than one-star typologies are connected or cascade.Features are same as the star topology.

Special or Hybrid Topology:
it is a combination of the different types of topologies.
For eg: -   We are using star and mesh topologies in same LAN.

Tree Topology:
it means the different departments are connected with a centralizing device like a switch.Features are same as star topology-

(B)Networking Model-
         It means the logical structure of a network.There are 3 types of networking model:-

1.Centralize or Server-Client Networking Model:


         It means the dedicated server will provide service and client will only receive service.

2.Distributive or Peer-Peer Networking Model:
It means all computers can act as server and client.

3.Collaborative or Hybrid Networking Model:
 It is a combination of centralizing and distributive networking models.
