Networking country easily, while using LAN networks

 Networking two or more computers
linked together to sharing information such as documents, E-mail or sharing
applications or at the same time they can share resources such as printers,
internet or storage etc…Or in Information Technology, Computer network called
as data network too this is a series of points, or nodes, interconnected by
communication paths for the purpose of transmitting, receiving and exchanging
data, voice and video traffic. To
make a network connection there are some most important
components we need such as Two or more computers, Cables, NIC for each
computer, switches and an OS (Operating System).These components are called as
Network Building Blocks. If we take the real world example for this so many
Multi-National companies are using network. Because they can gain so many
advantages from this for example they can share their product and they can
market around the world, they can share the file and can communicate from one
country to another country easily, while using LAN networks they can share the
resources so and so.

The most network
connection is made via electrical cable it means Ethernet and it’s able to
carry the information in the form of electrical signals but there are some other cases also it means,
Some network connections are made via fiber optic cables. Wireless computers
communicate via signals such as Radio signal, UV Signal.

Importance of Network…..

            If we consider a
network it works as a basement for an industry. The main advantages of a
network is connecting and sharing. These are the two main major purpose of a
network. Other than that we can get so much usages from the network. These are
main importance of a network:-

·       Cost reduction

·       Speed

·       High reliability by
having multiple sources of supply

·       Greater flexibility
because of possibility to connect devices from various vendors

·       Save time

·       Sharing resources

·       Sharing application

·       Sharing information

·       Sharing a single internet connection

·       Improve communication

1. Sharing Application…

This means we are sharing some important applications from one computer
to other computer. This is one of the most common reason for networking many
business organization is that several users can work together on a single
business application. So by considering this thing we can say that sharing
application is one of the most important to all users can work in a network.






2. Reduction of cost and time…

This produce a rapid method for sharing and communicating so it saves
times. Easily and safely we can done our works otherwise we need to spend more
time to share and communicate not only that but also if we Didn’t use networks
we need to save our files or applications in another CD/DVD/Floppy disc or if
we didn’t share the resources we need to buy resources for each nodes so this
cost much than that.


There are several ways
to design a computer network.
This refers to how computers are organized in a
system and how tasks are allocated between these computers. There are two types
of widely use network architectures:


2. Client/Server.

1. Peer to Peer
Computer Architecture:

           This is called as
P2P.In peer to peer network it does not use a centralized server which control
network activity. Instead here every computer have a special software running that allows for communications between all the
computers. Here all of them are considered equal / peers there are no
any special hierarchy. This networking has been built to all version of Windows
since Windows 95.

This is mostly used for file sharing. A
user makes some of the files on the hard disk drive available for sharing. This
will available to the rest of the users so they can decide if they want to
download one or more of these files. If a second user has downloaded a file,
this can also be made available to the rest of the users. So now there are two
possible sources from which to download the same file. This is the method how
file shares among thousands of users at a one-time download.

The Recent protocols for sharing files is Bit Torrent
but in earlier Napster is a file sharing network. This network is robust in the
sense that if one or several of the individual computers stop working for some
reason, the network continues to function. The quality of the network depends
completely on the contribution of individual participants. File sharing
networks that distribute copyrighted material, such as movies, music and books,
without permission. But since peer-to-peer networks lack a central control

2. Client/Server Network Architecture:

is also called as tiered. Here the computing model which the server host,
delivers and manages most of the resources and services to be consumed by the client.
Here there is a centralized device work. Here one or more client computers
connected to one centralized computer over network or internet. These shares
computing resources.  All the requests and services are delivered over a
network. Client computers provide an interface to allow a computer user to
request services of the server and to display the results the server returns
both client and server computers are considered intelligent devices, the
client-server model is completely different from the old “mainframe” model,
in which a centralized mainframe computer performed all the tasks for its
associated “dumb”





Terminals. The
server’s main job is to perform as a network this is a dedicated
one so the network which relies on dedicated servers is called a client/server
