NETWORK TOPOLOGIES

Topologies means any kind of designs that how we made our design understandable to the user or the people who want to understand our design of anything. Same thing is happening here in the IT world, there are many kind of network topologies.

    BUS TOPOLOGY :-

TERMINATOR:- In bus network topology terminator are used to absorb the signals.

BNC:- Bayonet Neill–Concelman, this connector is used to quick connect or disconnect radio frequency in coaxial cable. 

BACKBONE CABLE:- The central cable is called the backbone cable. 

This topology is very easy to install and also easy for foult finding. If the backbone cable get breaked than whole the network will stop. This is the main disadvantage of this network. 

                  

NETWORK TYPE

I have already told you about network and networking. So now today we are going to understand the different types of Network. 

 

LAN :-  LAN is the short form of Local Area Network. It is a network in which distance matter a lot. In a small organization LAN network is used. As the name says local area network means the network is only used locally. 

There are further many types of LAN 

PAN:- Personal Area Network this network is so much limited its area is only 1 meter to 3 meter. This kind of networks are only used at homes most of the time. 

SAN:- Storage Area Network, Any work performance by the user is stored in the backend is called storage area network. 

WLAN:- Wi-Fi LAN this is a wi-fi and its range is about 50-60 meters usually. 

CAN:- Campus Area Network. This kind of network is used in collages and university campus. 

MAN:- Metropolitan Area Network. This kind of network covered a city, mean the distance of this network is larger than other. Examples of this network is wi-max, cable TV and Bangalore city.

  

WAN :- Wide Area Network, as the name itself says that this network cover all over the world.  

LAN is further divide into two types 

WORKGROUP :- In it connection is point-point and no centralized control is present. 

DOMAIN:- In this kind of network communication takes place by the centralized control, means there are server and client technology used. 

Connection Medium

Medium is any thing that is used to connect two or more devices each other, that can be wired or wireless.
WIRED & WIRELESS MEDIUM :-
Wired medium is secured, faster and also costly than wireless medium. Range of wired medium is more than wireless because wireless devices has limitation of range but wired medium can be spread as our own choice as I mentioned above wired medium is costly this one is also a big reason of to be costly.

the upper on is WIRED and lower one is WIRELESS

I hope  I have make clear myself about wired and wireless mediums.

What is Internet ?

Hello everyone ! In the previous post I have already told you about Computer Networking.
I hope you all enjoy that and learn that. Now today I am going to tell you about Internet.
Internet is the network of networks, means all the networks of the whole world are indirectly or directly connected each other that's exactly called Internet.

 I hope its clear now with the help of this image.

INTERANET :- A network with in an organization or within a company is called the Intranet.
EXTRANET :- A network with in two or more organization is called Extranet.

NETWORKING CONCEPT

Hello everyone !
It was such very long time that we meet today. So friends today our goal will be understanding of computer networking. As you already know in now a days we can not do anything without the help of a computer. Before I start computer networking let me tell you first about networking.
Networking is a term, when two or more than two devices interconnected each other via wired and through wireless and can exchange data between each other is called networking. The most easy and most useful example of networking are roads. Stations are the devices and vehicles are data.
                                                                       In the field of computer networking is same as above, take a look again when two or more computers interconnected each other through wires and wireless and transfer data between each other is called computer networking. Now here a question arise that "why we need computer networking ?"
The answer is pretty simple and easy, with the help of networking we can save our time a lot, we can decrease our expanses, we can control a whole city, state, country, or world from a single place without moving from there. Take a small example of networking, let us consider a bank there are many computers use at bank but all of they uses a single Printer, they can send message to their manager or other worker of the bank without any internet connection.
               This is the little and brief understanding of computer networking concept. Hope you all enjoy learning.
