Local Area Network [LEN]

LAN is a Network which is small in size in comparison to MAN and WAN .It is limited within a building or a campus Local Area Network in which each computer is connected through LAN cables and they share data to one another. Local Area Network in other words are can say that the network within the local area or limited area is known as Local Area Network..!

Metropolitan Area Network [MAN] :-

A network little wider and larger than local area Network and spread over a city or town and network provide access to one another is known as Metropolitan Network..

Wide Area Network (WAN):-

The network which is spread over the globe and cover entire world, Wide Area Network is facilitated to a computer by Internet Service Provider. It is biggest network across the world in that each computer is connected and share or across the data and information. Wide Area Network is used all the way now a days for e.g. Finance sector , banking sector, banking sector, Share Markets and Many more. Through Wide Area Network . we can access the information stored for away on the web server in second. The Wide Area Network only thing we need is to known the address of that data or information Stored..!

The Wide Area Network can be in the following form................

Private Network
Wireless Network
Public Network

Wireless Network : Wireless Network are an important technology through which we access internet or local network computer or resource very easily. Wireless Network Now -a-days many of universities and industry campus are setting wireless router or antenna which is accessed through Wireless Network Bluetooth or VLAN..!

Public Network : Public Network are those network which are installed and run by the telecommunication authorities and are made available to any organization or individual who subscribe. Public Network Example include Public Switched Telephone Network (PSTN). public Switched Data Network [PSDN]. Value Added Service [VANs/VADs] and the Integrated Service Digital Network .[ISDN].......

Public Switched Telephone Network [PSTN] 🚀 :- The features of the PSTN are its low speed, the analog nature of transmission, restricted bandwidth & its wide spread available . Public Switched Telephone Network as PSTN is designate for telephones, modems are required when it is Public Switched Telephone Network used for data communication..

Public Switched Data Network [PSDN] : The term PSDN covers a number of technology, all through currently.it is limited to public Packet Switch Networks available to the public. The main features of all PSDNs are their high Label reliability and the high quality of the connection Provided. The can support both high & low speed at appropriate costs..!

Value Added Network Service [VANs/VADs] :- In values added services, the provider of such services must process, store and manipulate the data that is carried on the network, that add value to it. the technique can be used in specific types of business in which it is advantageous to be able to share information with other companies in the same line

Private Network : The basics technique used in all forms of privates WAN is to use private (or more usually leased) circuits to link the locations to be served by the network. Between these fixed points the owner of the network has complete freedom to use the circuits in any way they want. They can use the Private Network circuit to carry large quantities of data or for high speed Transmission..

Network Based on Management Method

Client - Server Networking : it is a kind of network in which computers are connected through client - server architecture. In Which client-server networking , there is a computer defined as server and number of computer is attached to that - server computer through cables and these attached computers can access the permitted information and resources stored on the server where as the server computer can access or do modifications in all the way with client nodes [computers] known as client -server computing or network..

Advantage of a Client/ Server network.......................

centralized-Resources and data security are controlled through the server :
Scalability- Any or all elements can be replaced individually as needs increase:
Flexibility - New Technology can be easily integrated into system
Interoperability - All components (client/network/server) work together ,and
Accessibility - Server can be accessed remotely and across multiple platforms.
Disadvantages of a client/Server network.....

Expense - Requires initial investment in dedicated server :
Maintenance - Large networks will require staff to ensure efficient operation ; and
Dependence - When server goes down, operation will cease across the network....

Peer-to-peer networking.......

Peer-to-peer networking system allow user to share resources and files located on their computer and to access shared resources found on other computers. However , they do not have a file server or a centralized management source . In a peer-to-peer networking .all computers are considered equal: they all have the same abilities to use the resources available on the networking for e.g. Torrents , we download a torrent file from the web and put this in queue to be downloaded then from whom or where you access as part of file is known as seed and your computer will be peer for that computer you downloading the data from...

Advantages of a peer-to-peer network...

Setup - An operating system (such as Windows XP) already in place may only need to be reconfigured for peer-to-peer operation.

Disadvantage of a peer-to-peer network.....

Decentralized - No central repository for files and applications and
Security - Does not provide the security available on a client/server network..
Network Based on Topology : The configurations of network components widely use network topologies Bus, Star, Ring, Mesh,. Here is the brief info of the Network Topologies.....
